Well I checked for Max connections on mysql.
Had nothing defined so I added: set-variable = max_connections=500 The problem remained So I incresead the value Same problem. Under Squirrelmail I get connection dropped by imap server. And Im still looking on the logs for something strange. I found this: Jul 23 15:48:30 mail spamdyke[7315]: ERROR: unable to write 26 bytes to file descriptor 1: Broken pipe Best regards, António Pedro Lima _____ De: Jake Vickers [mailto:[EMAIL PROTECTED] Enviada: quarta-feira, 23 de Julho de 2008 12:18 Para: qmailtoaster-list@qmailtoaster.com Assunto: Re: [qmailtoaster] server acting strange António Pedro Lima wrote: Im getting frustrated with this. Its getting more and more frequent that mail clients return the error: -ERR authentication failed Nothing was updated or modified on my QMT So I really cant tell what would make this happen What is your load like? This may be caused if you are reaching your maximum number of connections for mysql.
