Hello,
Hi Folks
We operate a central syslog server for several thousand system on a linux box running syslog-ng 2.0rc3. For some time we have noticed that the machine hosting the service slowly locks up and we then have to reset the power to restart it. Recently we significantly increased the load on the box and now this is happening about once a week.
2.0rc3 is a very old version. I recommend upgrading to 2.0.5 which contains a lot of improvements compared to 2.0rc3
Here are the symptoms we observer:
1. service to systems sending logs to the host are not affected. Logs continue to get written to disk 2. Cron jobs hang 3. login attempts hang 4. as do sudo attempts. 5. ssh sessions that were established before things turned to custard are not affected 6. top, sar etc. don't show anything unusual 7. ps shows hung cron jobs but nothing else unusual
Interesting... So syslog-ng doesn't hang, however new processes do? It would be useful to have the strace output of syslog-ng and a hanging process to see what happens. Could you check how many file descriptors are in use on your system when the problem occurs?
