The following options seem to have a direct impact on how fast I run out of resources (obviously) . The more I increase them, the faster I get the mmap error.
*mupdate_workers_start mupdate_workers_minspare mupdate_workers_maxspare mupdate_workers_max
I have them all set to the default values right now. * Right now my ulimit is configured like this:
core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 200000 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) unlimited cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited
and Im still getting the mmap error. Got it once this night... so far cyrus didnt throw any DBERRORs though
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 .
free output:
total used free shared buffers cached
Mem: 2074264 1805272 268992 0 94500 1331860
-/+ buffers/cache: 378912 1695352
Swap: 2096472 0 2096472My ulimit seems to be configured correctly.
Since I reduced the mupdate_workers options I've been getting lots of "cyrus/mupdate[22343]: Server too busy, droping connection." , which is deferring lots of e-mails on the postfix server.
Any new advices ?
