Re: [vchkpw] Vpopmail mysql and aborted clients
the warnings are daily... on sarge unless on etch yesterday in a testing machine I had a hang of courier and had to restart it by hand, but today have started mysqld_safe with --wait_timeout=345600 and haven't seen today any warning and courier has logged properly... I'm gonna check the two solutions... the wait_timeout increasing and the vmysql.patch... (that I think it come from vpopmail 5.4.17 to more newer...) thanks a lot mates :) have a nice day [EMAIL PROTECTED] wrote: Yes it really goes ok... and now for example the server has a uptime of more or less 110 days... I have never had to restart courier-imap package (wich I use for pop and imap services) and seems to be running ok... so this is normal then? and I shouldn't change nothing then? or is it advisable to increase mysql timeout?? or I could stay as I'm now? I would suggest setting the mysql timeout to about twice the longest interval between pop/imap logins. 4 or 5 days is probably good. One day wouldn't be bad if you don't mind seeing a few warnings on weekends. I don't use mysql though. Rick

Re: [vchkpw] Vpopmail mysql and aborted clients
So then no matter for worrying about this? This can't break the database or... don't know cause any type of problem... or should I do any conf in authdaemon for this to be avoided? or is this normal and nothing happens with it? Thanks a lot!!! As told in other messages, the way of playing is different. Each vpopmail/qmail program usually executes brieftly and opens and closes MySQL, so there are no abnormal exits. When courier plays (both imap and pop), it asks auth data to courier's auth daemon. When this daemon is started, it opens MySQL and never closes it, as it supposes to reuse continuosly the same opened connection. But if none is going to use the connection for eigth hours, MySQL itself closes the connection. This will be opened again automatically by vpopmail library in courier's daemon, but you see an error in MySQL stats. Hope I've been clear.

Re: [vchkpw] Vpopmail mysql and aborted clients
If your courier still works without you need to restart it, it means you already have vpopmail in the right configuration, and you are only facing a log warning (which reason is now known).

Either restarted authdaemon if this happens or upgrade vpopmail. This should not break the database. It just affects your imap connections. Or change your my.cnf for mysql to allow unlimited timeout's. That's what I did (Well I actually set it to 4 days). Rick

Re: [vchkpw] Vpopmail mysql and aborted clients
thanks a lot mates for you're answers, and in where logs could you see connections have been droped?? you doing an overview for all answers some mysql versions have timeout for it's persistent connections (connections as vpopmail connections) and this causes connection not to close properly and the aborted client... so then is a mysql issue?? could this cause problems?

All qmail processes run under tcpserver and are only invoked when a connection appears. courier has this authdaemon that maintains persistent connections to mysql via the vpopmail library and so its behaviour is different from being run under tcpserver in qmail-smtpd or qmail-pop3d. This is why it appears that courier is the problem but it actually is not. It is just that courier has a different way of being run and this was not taken into account by vpopmail because none of the relevant qmail processes run persistently.

I have asked sometime in courier mailing lists but they say me to ask at vpopmail mailing lists... and I know qmail and vpopmail both don't cause this aborteds because I have another machine in the same way configured (of course as the machine in wich this is seeing) but without courier because it's only for mail scanning and have any aborted client... each machine has it's own mysql server... and I'm totally sure this aborted happen when courier talks to vpopmail the first time after a inactivity period... is this normal¿? why happens this??

I thought this was addressed in a recent version of vpopmail? when vpopmail tries to do something on the sql server and gets a connection was closed error, it now opens a new connection and tries the operation again. it sounded like he was talking about seeing the stale client threads/ processes within the sql server itself, which for whatever reason hadn't been harvested by the sql server's reaper. if so, that question has more to do with the sql server's internals than it does with vpopmail. | John M.
