[Dovecot] Excessive dovecot-auth proceses

[Andrew Hutchings]

Hi Timo,
With auth_worker_max_count = 10, over the last 14 hours:

[root at svr24 root]# ps x | grep "dovecot-auth" | wc -l
29

[root at svr21 root]# ps x | grep "dovecot-auth" | wc -l
34

extract from svr21 pstree:

     ├─dovecot─┬─34*[dovecot-auth]
     │         ├─4*[imap]
     │         ├─3*[imap-login]
     │         ├─2*[pop3]
     │         └─3*[pop3-login]


Any kinda tests/debugging you want me to do?

Regards
Andrew
