I have a postfix (2.7) server where as soon as I restart the mails are
moved rapidly from incoming queue to active
But soon ( after 5 minutes ) the queue manager is left behind .. the
incoming queue keeps increasing 10k+ but active queue has hardly 10-15
mails
How many recipients in those 10-15 messages? What is the queue manager
doing (strace, truss, ktrace, ...)? I've seen cases (potential C-library
or kernel issue) in which trivial-rewrite does not see a new request
from the queue-manager until the queue-manager exits and only then does
trivial-rewrite notice the queue-manager's lookup request. Report any
warnings, or fatal messages logged by trivial-rewrite or qmgr.
Is there a known kernel issue .. I am using a centos.plus kernel on 64
bit.
( rpm kernel-2.6.18-194.32.1.el5.centos.plus )
This performance is not consistent. Today the mail server is working
just fine.
The number of mails transacted are almost the same but there seems to be
no issue now.
Initially I had a similar issue but that was due to syslog , ( I had
dabbled with syslog-ng .. then reverted to syslog and all was fine )
But I would love to find the root cause why the queue manager is left
behind at times.
Thanks
