[syslog-ng] Syslog-ng too many open files

Try raising the per-process number of open files. Please refer to
ulimit.

This raises the per-system limit only. per-process limits still
apply as well as the maximum (maybe 4096, I'm not sure) is hardcoded
into the kernel, so without recompiling you r kernel you can't exceed
this limitation.

Without seeing more details (syslog-ng version number, configuration,
approximate number of clients, client configs) we could only guess.
