[syslog-ng] Syslog-ng appears to hang for local requests to log

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 kernel: warning: many lost ticks. kernel: Your time source seems to be instable or some driver is hogging interupts kernel: rip default_idle+0x20/0x23
