Courier IMAP: "malloc: Input/output error"
Hi all,
I have only just recently started receiving the following errors in my
mail server's mail and system logs:
Apr 5 15:11:38 tarquin.lan imapd-ssl: malloc: Input/output error
Apr 5 15:11:38 tarquin.lan imapd-ssl: malloc: Input/output error
This is repeated a lot, but only appears for imapd-ssl and no other
process. Note that I'm only allowing outside IMAP connections over SSL,
so this may also happen for imapd, but since it's hardly ever used it's
not causing errors.
At first it could be my swap partitions failing but nothing else seems
to be going wrong and 'badblocks -vw' can't find a thing...
I'm using a virtual domains setup, so all of my users' mail is stored
and accessed using the 'vmail' account on my system. Some googling found
someone thinking it could be about ulimits, and another post on the
Courier mailing list, but couldn't find answers to either...
I'm using a homebuilt kernel 2.6.11.5 with grsec. The system has plenty
of free memory and a humongous amount of free swap...
Any ideas?
Many thanks,
Chris
