Greetings, This is not a problem with Samba as I see it but I am hoping that others on the list have some ideas for working around the issue. Our central computer services group scans all the campus networks using Nessus and some custom rules to look for security problems. What I am seeing within my college is my Samba PDC getting beat-up when the scans go though. They scan a block of PCs

...tem at around 1.5 MB/sec, network connectivity suddently started to show signs of lag. The ping would spike up to ~1 second every 5 seconds or so. This affects the server in question and all hosts routing traffic through it (i.e., it's not a userland-only problem). When this happens, the load skyrockets (> 10 on an otherwise mostly idle server) and kjournald can be seen consuming CPU cycles like mad. When the write to the file is paused, the problem immediately goes away, and then resurfaces. This is on a 2.4.19 kernel. Is this a known problem with ext3fs? Granted, we cannot be sure ext3fs i...

...encing). It would be useful to allow me to force the remaining nodes to just understand the node was taken down purposefully, and move on with their lives. A real world example: OCFS2 hosting files used with a website, driven by Apache. If a node goes down, the load average on all remaining nodes skyrockets to 500 or more, as the Apache processes all enter a state of uninterruptible sleep. This triggers alerts, pages, and on occasion, application specific triggers (web app) that show a "Too Busy" page when the load average is too high (for instance, that which vBulletin does). It would be m...

...on my desk using rsync. I've attempted to do this using a Raspberry Pi as a remote device, but when I set it up the dovecot replication process seems to need to start the replication over from scratch even after the rsync is done. I know this is happening as the disk utilisation on the Pi skyrockets once the replication starts and I end up with thousands of double ups of all the mails ... which defeats the entire point of the process. If I do an identical configuration but on a third Gentoo x86_64 VM locally it all works as expected. No double ups of mails and the "catchup" be...

.... Everything seems fine until midday, then what we start to see is the number of smbd processes going up whilst the number of connections (determined from smbstatus -b) dropping, students with connections starting getting slow responses and no new connections are being made, load on the system skyrockets. stopping samba and restarting seems to cure the problem, but the problem can re-occur. We are in a desperate panic at the moment as the students are all doing assignments and this is seriously affecting their work. We have tried various tweaks to Samba (deadtime, change notify timeout), the tcp...

So far we've tracked down four bugs using _GLIBCXX_DEBUG, all of them quite subtle and some of them leading to serious problems like heap corruption. But we've also discovered that compile time can skyrocket in some cases as the library does its checks. The standard library complexity guarantees don't apply with _GLIBCXX_DEBUG. Therefore, we should figure out if we want to enable

I'm trying to use Wine to run a program called heavy weather - its a windows only program that interfaces with a weather station that I have through a serial port. I was able to get the program up and running with wine. Then, I couldn't get it to connect at all to the weather station. After much too long, I finally realized that the problem was that my permissions on /dev/ttyS0 were too

We run a Hosting farm behind a bridge/iptables firewall setup running Gentoo with kernel 2.4.20-gentoo-r6, connected to a dual 15Mbps international internet pipe / , as this: Net Pipe --------- eth1 Bridge/Firewall eth0 -------- Internal Hosting Network lately we have been looking at htb to somehow control excessive usage from the users behind, but in our implementation there seems to be an

We have a "compute cluster" of about 100 machines that do a read-only NFS mount to a big NAS filer (a NetApp FAS6280). The jobs running on these boxes are analysis/simulation jobs that constantly read data off the NAS. We recently upgraded all these machines from CentOS 5.7 to CentOS 6.5. We did a "piecemeal" upgrade, usually upgrading five or so machines at a time, every few

The raid check starts out fairly fast (20000K/sec - the limit that's been set), but then quickly drops down to about 4000K/Sec. dev.raid.speed sysctls are at the defaults: It looks like some pretty heavy writes are going on at the time.

...can connect. Top shows a few smbd processes maxing out the cpu and the load (which is usually < 1.0) gradually climbs up to 10, 20, and onward. If I stop smb and winbind with the init scripts, then the load goes through the roof. I've waited to see if it will clear itself up, but the load skyrockets up over 1000 so I kill all the smb processes with "sudo kill -9 `pgrep smbd`" and then the load stops climbing and after about 5 or 10 minutes will be back down to under 1.0. At that point I can restart smb and winbind and everything is ok again. I don't see anything unusual with...
