similar to: poor performance with dom0 on centos7

Hi Im now pretty sure the problem is the DomU with NFS Server. If I write on a NFS share from other Host (bare metal or other vm) then I see on my NFS server nearly the whole time 100% io at [jbd2/dm-5-8] process... If I write on a SMB share (same partition as nfs share) from other Host then it is a little bit better but still ever and ever again 100% io load If I write a 1GB file on the

Hello everybody! Currently, dovecot just kills itself if it detects that time has moved backwards more than a hardcoded number of seconds. I accept the reasons, but I do not like to restart dovecot manually after waiting for time to move forward again. A cron job would not help, because time might still be wrong when it restarts dovecot. All our systems run ntpd, but they might be offline

Hi list, I have a problem with Mongrel which is really bugging me. I would really appreciate any help that anyone can provide to help me in solving this problem. 1. My setup: Apache front_end with mod_proxy_balancer in front of 4 mongrel/rails instances of my application. Rails 1.2.5 Ruby 1.8.6 Mongrel 1.1.1 2. I noticed that the CPU consumption on my server was 100% being consumed by ruby so I

Hi all! I have tried the imap_acl plugin with 1.2.9 today, but was not able to limit acl changes for those mailboxes where acl changes should be forbidden. http://wiki.dovecot.org/ACL says that "a" or "admin" covers "Administration rights to the mailbox". However, removing "a" from owner acl (using "lr") does not help, the user can still

Prevent xl from doing any operation if xend daemon is running. That prevents bugs that happened when xl and xend raced to close a domain.

Hi I have a rather strange problem with mongrel and I would be grateful if anyone could assist me with resolving. I have an application running mongrel 1.1.1 and rails 1.2.5 with ruby 1.8.6. It was all working fine and starting as expected. But I did a server reboot once and mongrel has refused to start up since. I get the following error:

Hi folks, first of all thanks for Dovecot, I appreciate it a lot. On one of our servers, we experience regular tries to brute force logins, probably based on harvested mail addresses. Now I wonder if dovecot has or could in future have some mechanism to blacklist remote IP addresses after a configurable number of failures to login to any account. Blacklisted IPs could simply be disconnected

Hi all, I am interested in building a stand alone Rice Encoder/Decoder, using FLAC source code as a starting point. I've read the theory behind it, and I am very interested in info theory. However, I am struggling with how exactly I would implement the theory in code. I'm a newbie to computer science (only 1 year experience). I have read the format and documentation links on the FLAC

Hello all, Recently I have received a few complaints from users that their quota was being reported wrong. This seems to have started when I switched to quota=maildir and ignore=Trash (did both at the same time). The main reported problem is that maildirsize is not correctly updated when they delete messages. My personal hypothesis is something like this: - User moves to Trash - Trash

Does someone know, if in the new release of dovecot 2.x.x there is a feature implemented, that wakes fetchmail or any other program on a client request, or is the "fetchmail wakeup" plugin still the only way to do this (at least I've not found any other, and that plugin never worked for me),.. Yours Peter

I converted a system disk from a virtualbox VM and added to the config on a qemu VM. All seems well until I try to mount it. The virtual machine shows data for the disk image using commands like: pvs lvs lvdisplay xena-1 but there is no /dev/xena-1/root to be mounted. I also cannot seem to figure out whether the lvm related modules are available for the virtual machine kernel. Has anyone

This an open plea for someone with knowledge of RubyGems to explain why RubyGems stays in memory (over 10MB) after a Rails application is loaded. I am unable to figure out why this would be necessary. I haven''t had any response from Jim or Chad from RubyGems about it so I thought I would throw it open to the list to see if anyone could educate me or share thier experiences with this.

Now supported by v2.0. Also as a patch to v1.2: http://dovecot.org/patches/1.2/zlib-compress.diff I'm not really sure if I should commit it to v1.2 code tree.

Hello, Recently, I've spent the last few days trying to get some unix client boxes to authenticate logins via winbind, so all of our unix system accounts can be maintained from active directory. So far, everything is working, and users can authenticate into the system, but they are assigned random uid/gid values, based on the smb.conf as well as the internal winbind_idmap.tdb file.
