It's nice to read from a TBS legend.
We are currently undergoing low resources here and there from time to time.
dloser is doing his best to keep the stuff operational and i am thinking of a server upgrade.
Current problem was "non-tcp-sockets" exhausted... I added a restart to imap and smtp, maybe postfix or dovecot hog those connections (this is a shot in the blue)
Some days ago crawlers or bots hit us hard. probably chinese crawlers. dloser added a few iptable rules to keep the site up.
All in all we currently have stability issues.
Sorry for the inconvience!
