Hi Zhang,
I'm in serious trouble to update an old iRedMail (v. 0.7.3) on server, so I can install the new version of iRedAdmin-Pro-MySQL (I've done this update on another server without any error).
On upgrading from 0.7.3 to 0.7.4 I created a new database table vmail used_quota and adjusted the parameters in the configuration file dovecot-used-quota.conf, replace "table = mailbox" with "table = used_quota".
So when I restart the Dovecot messages start to accumulate in the Postfix queue and server load goes up too. So the service is unstable.
Checking the log Postfix noticed something strange in Dovecot (log attached).
Note that the Devecot "delay" increases much staying out of default and begins the error "temporary failure" appears.
When I return to the original configuration (table = mailbox) and restart Dovecot, back to normal.
I've done the setup a few times because I could be missing something, but in all the same behavior occurs and I have to go back.
I realized that Dovecot is usually connecting to MySQL because it began to be recorder data in the new table used_quote before the server destabilize (high load and temporary failure).
What can be happening?
Tks
