similar to: High level of pop3 popping causing server to become unresponsive

Hello all, I hope someone can help me, I have been testing out Dovecot to switch from popa3d which I use at the moment. When I get several users connecting and disconnection multiple times, the Dovecot process with command Auth uses 50-90% of the CPU for the period which they are connecting. I am wondering if there is something that I may have misconfigured, or if there is something that I can

Hello Group, We have dovecot deployed as solely a Pop3 service that is used by our applications to pass mail from one application to another internally. We have roughly 4 applications that connect to the Pop3 service every 2 seconds, to check for new messages and pop them for processing if they are present. Depending on the site, we have between 1024-2048MB of memory set for default_vsz_limit.

Hi, I have a web server which is randomly becoming unresponsive. I've checked for hardware problems with no luck : - no ethernet errors - no disk errors - no memory errors So far I've managed to point the trouble at the web server since if I restart httpd (apache) it comes back to normal. This is not a shared server so I control (or at least like to think of) what is hosted so I have

This is a strange problem I can't seem to wrap my head around. I have a server with 2 interfaces. Samba is serving happily on one, and will remain on a single interface (eth0, subnet A(/22), vlan 101). I wish to bring up a second interface (eth1, subnet B(/24), vlan 102) that will be serving up nfs and ssh traffic only. Currently, Samba will process requests from any computer on the

We are running asteriskNow 1.4.18 and after a few days it becomes unresponsive and inbound INVITEs timeout. We just reboot the box to resolve it. But it seems to be occurring more regularly now. I am hesitant to move to latest version, but will do if needed. Any guidance or troubleshooting modes I may use will be helpful. -------------- next part -------------- An HTML attachment was

Hi everyone, I have a problem with puppet-dashboard because I appear unresponsive when many nodes are running correctly. In my current configuration nodes do not run the daemon, but I have created a cron task that runs once the command puppetd at hourly intervals. The point is that when I look into dashboard many nodes are always considered unresponsive because it seems that the default dashboard

Hi guys, I have a strange situation. I''ve got 1 dashboard MySQL DB accessed from 3 different dashboard hosts. Strangely enough, 2 of them show the right node statuses, and the third one just shows all nodes as unresponsive. As far as I know, the status comes from the "nodes" table in the DB, so how can this happen? Is there some cache I need to clear? Is there another

I'm having an issue with an apache web server running the latest CentOS5 kernel (this issue is not new to the kernel). After a few days/weeks of running the server will become unresponsive and will require a physical reboot in order to come back online. The system is so unresponsive when the issue occurs that login at console is not even possible. I have atop installed and have looked back

I am using the Mate desktop on CentOS 7 and have found that the mouse intermittently becomes unresponsive for a few seconds, typically no more than 3-5 seconds. I do not remember seeing that when I used the regular Gnome desktop on CentOS 6 but I could misremember. The machine is fast and uses a dual-monitor setup with the native nVidia graphics driver. Is this really to be expected? I thought

Hi, I set up my application on Linux (Suse), running MySQL (which sits on a different server) and Webrick. It works fine. However, every morning when I come back to my desk, the application gets unresponsive. If I simply access http://host:3000 <http://host:3000/> I can see the rails greeting page (that means Webrick is running fine right?), but if I access any of pages in the

Hi all, I would like to know how to debug xen. To give some more informations, I would like to explain why I''d like to do this. I''ve compiled xen from source (3.1.x/unstable) and installed it on Debain etch. Furthermore I''ve installed 2 DomU, one HVM (Win2k3) and one EFW (Endian Firewall, RH-based 2.6.9-55 kernel). Both DomU''s are running fine for about 15

We have been experiencing a debilitating 'bug' in samba where something is causing a flood of the messages seen below in smbstatus and the network drives ( in our case N: ) on all clients become unresponsive. In fact, the entire client becomes unresponsive, essentially making them unusable until samba is restarted. We first saw this and connected it to the following open bug in samba

I am having some unresponsive and very slow performance with a couple of different file types with Samba and Windows 7 clients. The problems manifest in the following manners: IGES files, these are CAD files. When opening up certain IGES files from the server, the application can take upwards of 10 minutes to open up the file. If I copy the same file from the server to the desktop, the

Ok, we used to get this occasionally on cluster nodes, and we just got it on a fileserver (very bad). The system is discovered to be unresponsive: it doesn't ping, and plugging a console in, you can see that it's not dead, but there nothing at all on the screen, nor does it respond to even <ctrl-alt-del>. The only answer is to power cycle it; it comes up fine. Nothing in

/etc/samba/user_and_group_map.txt contains Windows username/group to linux username/group mappings. In our setup, all users exist in ldap, as do the directory groups, but the linux user and group information (namely uid/gid) do not. This has been setup such that the users connect to samba as the windows username (ex. PRODUCTION+user1) for an authroized group (PRODUCTION+group1), but the files

Hello, I'm sure there is no good answer to my question, but it doesn't take much to ask, so I will. I am about to migrate my current Dovecot IMAP + Popa3d mailbox server to Maildir. I need to keep both protocols (IMAP and POP3) and will be switching to Dovecot on both. The question is simple - is there any way to keep POP3 UIDs through migration, so people won't get duplicates

OS: Linux (Linux ares 2.6.22-3-686 #1 SMP) Dist: Debian (testing) UPS: Tripp Lite Omni1000 LCD After updating from 2.2.0 to 2.2.1, the following command seems to go into loop and becomes unresponsive except for a "kill -9": /lib/nut/usbhid-ups -u root -DDD -a trippy It seem that the previous version would pause the output at some polling interval, but with the new version prints to

Hi all, sorry, I don't know where to write, I hope here will be the correct place. I am using Wine 1.2.3, in Mac OS 10.7.3 (LION) and was working fine, before I try to open the menu and choose WINETRICKS, the window open and freeze the app, an turn it unresponsive, and now I don't can use Wine or Cross Over, I uninstall all wine, wine bottler and cross over, and install wine again but same

Dear R Help, I've just installed 1.7.1 and have found that the console now exhibits odd behavior when I paste commands into it. I'm on a PC running Windows XP Professional. I use Word as my script editor, and then paste commands into the R console using the standard Windows "copy" within Word then "paste" within Rgui. This worked without a hitch in 1.7.0, but now in

very similar, only two are weird: 1st from MacOSX my (laptop) and from Windows running perfectly, never interrupted. 2nd To the solution was not within this thread, and I do not believe that it is impossible to solve.
