dovecot - Jan 2012 - more than 200 imap processes for one user

HI,

recently I noticed, that our dovecot server (RH EL 5.7
dovecot-1.0.7-7.el5_7.1) 'fires' up a lot of imap processes only for one
user.

I counted 214 :-) most of tham in the 'S' state and are started nearly
at the same time within 5 minutes.

Usually users do have about 4 to 10 ....

Dose anyone has an idea, what could be the cause?

Thanks for any suggestion and best regards . G?tz

v1.1+ limits this to 10 processes by default.

Some client gone crazy.
