Im again in a point that I just dont know where to look for problems
anymore. System resources seems to be fine, yet Im getting the dreaded
"Cannot allocate memory" IOERROR .
total used free shared buffers cached
Mem: 2074264 1805272 268992 0 94500 1331860
-/+ buffers/cache: 378912 1695352
Swap: 2096472 0 2096472
My ulimit seems to be configured correctly.
Since I reduced the mupdate_workers options I've been getting lots of
"cyrus/mupdate: Server too busy, droping connection." , which is
deferring lots of e-mails on the postfix server.
Any new advices ?
