It's really a mysql-question - but I'll ask anyway: If I have a .my.cnf in ~root and a my.cnf in /usr/local/etc - which one get's used ? Or do they get used both ? The one from ~root is mainly for some backup-scripts and doesn't contain any tuning-options. Or will both get used ? cheers, Rainer -- === ~ Rainer Duffner - [EMAIL PROTECTED] ~ ~ Freising - Munich - Germany ~ ~Unix - Linux - BSD - OpenSource - Security ~ ~ http://www.ultra-secure.de/~rainer/pubkey.pgp ~ ===

You are either using more mysql connections than the default or your mysql server is over loaded. > Somebody have a configuration of mysql for high concurrency and that work > with vpopmail? I agree with Rick, use the large configuration file. Unless you are running a mysql cluster I recommend commenting out the "log bin" line. You might want to use InnoDB tables, which I think are the newer ones, then uncomment all the inno_d lines. > Is possible limit vpopmail for don't use more of 100 connections? I think the default max connections are 100. So just give more to mysql, like Rick suggests. > Because it reboot my mysql daemon I'm not surprised. Hopefully the max_connections are your problem and everything will run smooth. If mysql is still lagging you will need to consider a cluster of servers and distributed mysql. > Should I think use postgresql instead of mysql? First, fix the max connections. mysql should do fine. I wonder is there any documentation on how to setup email/mysql/nfs in a cluster? I would be willing to contribute text. Ken Jones
