I have recently inherited a bulk mailing system from a recently acquired
company. All systems are running kernel 2.4.1 pre9 with reiserfs used on
the /var/qmail/queue partition.
Qmail version 1.03 patched with qmail-103.patch and the qmail-nosync.patch.
Concurrency set to 255. Here is the issue Our db of 3million+ users is
split between the 3 servers and a perl script is run and each message is
piped to sendmail. Now The first time I used the system it worked
flawlessly. I have since found that when I run the script Qmail sits on the
messages and fills up the queue. For example on one system the
/var/qmail/queue partition now at 100% hold 809000 msgs only one
preprocessed. On top of this the memory has completely filled up as well..
Seems to be a memory leak.. Because when qmail is stopped the memory is not
relinquished. My two question are why doesn't qmail immediately start
sending out the messages in the queue and what is causing the leak. is it
qmail or most likely the 2.4.1 pre9 kernel?
