Hello,
running 0.99.10.6 (but seen it before that, too). Also (quite obviously) running 5 auth processes, given the fact that this is a pretty busy box and I didn't want to introduce any artificial bottlenecks. Alas with them eating up half of the free memory (which would go to a much better use as FS cache) I'm getting sorta concerned. If it's not a leak, it's caching something rather needlessly and inefficiently (the LDAP DB memory footprint for ALL users is less than this and the box below just serves half of those). This box sees about 0.5 million POP3/IMAP logins/day.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 31235 root 16 0 220m 216m 5560 S 0.0 10.7 25:01.54 dovecot-auth 31234 root 16 0 205m 202m 5560 S 0.0 10.0 24:08.84 dovecot-auth 31231 root 16 0 200m 196m 5560 S 0.7 9.7 23:25.37 dovecot-auth 31232 root 16 0 196m 192m 5560 S 0.0 9.5 23:10.44 dovecot-auth 31233 root 15 0 179m 175m 5560 S 0.3 8.6 22:13.07 dovecot-auth
So, I guess my questions to Timo are:
Think it's leaky and any idea where?
Given the load, would a single auth process be a bad idea? (it is a quite fast dual opteron box)
