I'm running syslogd-1.3.31-6 on RH6. I'm running it as syslogd -m 0 -r It is receiving log messages from two other systems (one is RH4.2 and one is RH4.1). After running for almost 2 weeks, the data size reaches about 11MB.
Grab the latest glibc from Raw Hide, or turn off NIS/NISplus in /etc/nsswitch.conf.
