Summary:                    DB connections not closed
Description: 
Hi

When many emails are sent (dbmail-deliver), connections to the DB are not
closed and many are "sleep"

It leads my system to have about 400 connections of dbmail to mysql, among
them maybe 10 are active. 

I set to 50 the limit in dbmail,conf

I suggest to verify the connection management to Mysql (maybe use only few
'permanent' connections (i.e. reuse existing connections) )

2.3.3 is the version, not 2.3.4

Why do you have so many dbmail-deliver processes running? They should
normally be short-lived processes, and thus shouldn't be able to keep
database connections alive for very long.

I do not have many dbmail-deliver running (the supervision shows up to 3,
based on Postfix policy)

but the threads seems keeping running connections, and mysql reports about
hundreds connections, and a "show processlist" make a large list of
"sleeping" dbmail

(cf below, I remove the processes not linked to dbmail)

The problem shall come from dbmail-deliver (I am not using dbmail-lmtp)

please don't paste logs. Use the fileupload. This report is quickly
becoming unreadable.

that said. I'll look into it.

Those open connections cannot come from dbmail-deliver, since that is
typically a very short running process.
If you could catch the last query for such sleeping connections that would
at least give me a hint where to look.

hey, the issue is still there and no way to get any "last query" (or please
tell me how to do that).

What version have you last tested this on?

Try using syslog_logging_levels=511 in dbmail.conf. That will produce
massive amounts of debug output.

I made it, but it is mostly impossible to figure out wich mysql statement
are linked to the 400 connections pending !

Is it possible to go from the other side, and check the "db_close" in
dbmail-deliver binary ?

dbmail-deliver cannot and will not generate 400 connections. I repeat
myself: it's a short-running process.

Try:

cat testemail.eml|dbmail-deliver -u youruser
grep deliver /var/log/mail.log
