Server during work time, is very very busy Before change postfix master.conf configuration, I have: lmtp unix - - - - - lmtp wich I belive it's the defaults 'cause I didn't changed them. Like this it's unlimited right? Tunning to: lmtp unix - - n - 3 lmtp means that postfix will only have 3 lmtp process's to dbmail, right? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul J Stevens Sent: quinta-feira, 4 de Outubro de 2007 10:34 To: DBMail mailinglist Subject: Re: [Dbmail] CPU LOAD Jorge Bastos wrote: > Wait i got something from one os the dbmail-lmtpd processes, see it this > tell's you something? > > fcntl64(6, F_SETLK64, {type=F_RDLCK, whence=SEEK_SET, start=0, len=1}, > 0xbffcdd84) = 0 That's the process pool's locking code. How many lmtpd processes are you running??? You will rarely need more than a few lmtpd processes (2-4), unless you have a very busy server. Even then: excessive amounts of lmtpd processes or even multiple simulaneous dbmail-smtp based injections can lead to deadlocks in mysql during message insertion. I've been trying to fix that recently. Update to the latest in the 2.2 branch to include those changes. Your problem is not caused by any post-rc2 changes. Narrow your lmtp bandwidth by tuning the maxproc field in master.cf: lmtp unix - - n - 3 lmtp on your receiving postfix installation. -- ________________________________________________________________ Paul Stevens paul at nfg.nl NET FACILITIES GROUP GPG/PGP: 1024D/11F8CD31 The Netherlands________________________________http://www.nfg.nl _______________________________________________ DBmail mailing list [email protected] https://mailman.fastxs.nl/mailman/listinfo/dbmail _______________________________________________ DBmail mailing list [email protected] https://mailman.fastxs.nl/mailman/listinfo/dbmail
