[Dovecot] LDA misbehavior?

[Eugene Paskevich]

Hello,

Could somebody please give me a hint on what might be going wrong?

line 1757 (mailbox_transaction_commit_get_changes): assertion failed: (ret  
< 0 || seq_range_count(&changes_r->saved_uids) == save_count)

error message)

It started a couple of days ago.
Triggered by the mass delivery.
E.g. by
for i in {1..50}; do { mail -s "test $i" eugene at hopper.volia.net <<< "Try  
$i" & }; done

I suspected that sieve might cause that, but disabling it gave nothing.

   }
}
ssl_cert = </etc/dovecot/dovecot.pem

}

Is there any other info I could provide?
