<div style="word-wrap:break-word">Hi,<div><br></div><div>I examined my mysql problem a little more and got the following:</div><div><br></div><div>the following log (2) shows, I preforked 7 imapd -s childs (by /etc/cyrus.conf) and while one of the processes still reads from the local mysql server (see process 32711), newly forked imapd childs are loosing this ability (see process 9881). From this time on nearly all newly created childs can't connect to the mysql server (even then when the "good ones" = 32711 are terminated). </div>
<div><br></div><div>In a very rapid process ( because childs with connection errors are terminated see log 1) new childs are forked and forked (in my case 1 fork/second the next 2 minutes - as well imaps as https processes) until without restarting the master process some childs are forked, which are again able to connect to the mysql server. But the forking process goes on and tries to reach the number of preforked childs. This fills the logs because only any then and now a "good" process is created.</div>
<div><br></div><div>But only if I restart the master any child is working. The default max connection limit is set to the default (150) for the mysql server. This is still a testing environment with only one user connected by one open mailer.</div>
