I just joined the list after seeing in the archive the syslog-ng causing other proccesses to freeze I've seen the same issue in syslog-ng-2.0.2. I also usualy see some error about exciding the maximum number of open files for root. if i happen to be loged in to the box as root I've been able to fix it by restarting syslog-ng. if ive been loged in as my normal useri can usualy run a sudo lsof but when i count the number of open files its onwhere near the number set in /etc/secutiy/limits.conf. i also ocasionaly see this in the logs right before it happens I'm now pretty sure that my problems are not related to file handles -- syslog-ng seems to have a builtin limit of 1024 open file handles and nev er goes over according to lsof.
I have just upgraded to 2.0.5 but another thing has just occurred to me. I have a destination fifo which is used intermittently. Fifo has an 8KB buffer and I just wondered what happens when this fills. Do writes from syslog-ng fail? If so does syslog-ng then try and buffer output itself? If so that would explain what we are seeing. If the new version does not fix the issue I will try disabling the fifo destination. Russell.
