[Dovecot] dovecot-uidlist: Duplicate file entry at line

[Luca Palazzo]

Hi Timo and All,
please take care of this trace. It seems that dovecot.uidlist's increase 
its size (8056 from stat and from read and then 14641 with stat) while 
delivering and then it tries to look for duplicates.

I hope this helps, duplicates problem is becoming big.
Can I check or trace something else?

Luca
