this probably means that rsyslog is not keeping up with the volume of logs

at this point 5.6.3 is a bit old, newer versions are probably faster and may
solve your problem just from being enough faster to keep up with the
incoming logs.
Pushed up to 5.8.1 and I still get the same amount of memory use.
iostat and cpu use seem reasonably sane, though at peak times most of
the threads peak to 99% CPU use.
sorry, I forgot to ask, does the iostat -x option show any of the drives
peaking at 100%?

Subject: [rsyslog] High memory use by rsyslogd - 5.6.3
Rsyslogd is using 1.4G of resident memory.
Here's my config snippets: http://paste.nothing.net.nz/806cba
There's 14 hosts sending data to this rsyslog server.
I've tried setting a ulimit
(syslog soft stack 1024)
via pam & /etc/security/limits.conf
and ulimit -a as the syslog user shows
stack size (kbytes, -s) 1024
Yet top clearly shows using 1.4G of resident memory:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
16414 syslog 20 0 2006m 1.4g 1252 S 0 72.1 1:28.83 rsyslogd -c4
my rsyslogd version is rsyslogd 5.6.3
Any advice is welcome.
