Random issue on mailbox "assertion failed"

[Thomas Durand]

Hi,

Since few weeks, I have regularly the issue below with some mailboxes - This is happening randomly.  Users are complaining emails are not visible. The situation is recovered by removing indexes but I would like to have it fix permanently.

Ruuning dovecot 2.2.10 - Anyone to advise me what is wrong ?

Thanks.
