authdaemond: fork: cannot allocate memory

[Mole]

Hello!
Today I receive this error ir /var/log/mail (mail.info, mail.err)

...
Jun 29 22:32:41 websrv pop3d: Connection, ip=[::ffff:_IP_]

So - nobody can login into their mail account! ;-(((

With disk size all is OK... What else could be the problem?!

[Mole]

sorry, problem solved with:

websrv:# authdaemond restart

khm...

but - where was problem?

Looks to me the server ran out of memory at that point .. how much ram you have? is it a VPS?

authdaemond tried to start a child process which it couldn't because it couldn't allocate memory for it, so it stopped and gave the error in the logfile.

When it happens again run:

free -m

you should be able to see the amount of memory you have - used - free
