cyrus/mupdate[12614]: IOERROR: mapping /var/lib/imap/mailboxes.db file: Cannot allocate memory
Resource limited memory, or are you really running out of memory?
Letting processes continue running in the face of an mmap failure needs to be re-examined I guess.
Hello again.
I've been trying to tweak all sorts of system configs in the last few days but it didnt help much.
I changed the following options because I was getting: cyrus/mupdate[18200]: Server too busy, droping connection.
mupdate_connections_max: 1024 mupdate_workers_start: 40 mupdate_workers_minspare: 16 mupdate_workers_maxspare: 80 mupdate_workers_max: 400
with mupdate configured like that my mailboxes db is getting corrupted once a day. If I decrease the values it will last longer, but I'll start getting the Server too busy error.
I've noticed that once I get the mmap error, the system will still run without spitting db errors for anywhere from a few mins to a few hours. Also, I never get more than one mmap error before the db becomes unnusable.
Not sure If I mentioned this before, but after getting the mmap error I can no longer restart my master because ctl_cyrusdb wont be able to recover the db.
What Im planning to do next is get a new server, install debian in it ( Im using Fedora core 2) and see if I have the same poroblem.
Regards,
Jo�o Assad
