[Dovecot] Random timeouts on mailboxes

[Bastien Semene]

Hello,

I tracked the processes number and it was very close to the limit, I 
read your link and think it is the solution to my problem.
I modified the config to fit our needs. No problem yesterday and today, 
it is rare but happened so I can't be affirmative, therefore the number 
of processes reaches the previous limit today.
I'll give some feedback to the list if the problem is still here.

Thank you Andreas for the idea but TB is installed locally and I think 
Steffen's answer is the good one. It fits perfectly with the symptoms.
