We have upgraded the dovecot from 1.0 to 1.2.8. After upgradation we have noticed that dovecot deliver process is utilizing a lot of CPU. As a result the mailsystem will stop working. When we limit the no of procs in postfix for dovecot deliver the CPU usage will come down. But we are not facing this problem with the previous version. Below is the log files for dovecot when the error occurs
You mean a single deliver process can run a long time with 100% CPU? Getting a strace of the process could be helpful.
Yes, dovecot deliver process is eating a lot of CPU. please find my strace output on the below link.
write_full(/home/vmail/dhanbank.co.in/vinukumarvm/temp.server.be3e5a849a909847) failed: No space left on device dovecot: deliver(user@example.com): stat(/tmp/Dovecot Delivery Mail) failed: No space left on device
But my system has 54gb of free space for root filesystem where tmp residing. Can anyone help me to solve this issue.
The /tmp/ part is wrong, I should get that fixed probably. Is there space in /home/vmail? Or do you use filesystem quotas? (I see you're also using Maildir++ quotas.)
My home partition has 353gb of free space. I am using maildir quota not using filesystem quota.
