Dear all,

We are running Dovecot (on debian etch, Version 1.0.rc15-2) on 4 Loadbalanced servers using a NFS share for the homedirs. The loadbalancer is using persistant connections (timeout 30min).

Lately, IMAP Users (mostly using Thunderbird) reported the following errors:

1. When trying to mark messages as read, nothing happened, message was still displayed as unread. 2. When moving a Directory the client loads for a long time and then hangs. Same was reported to happened when a user tried to open a mail.

When checking the logs at the time users reported those errors we could always find one fo the following "assertion failed" errors:


file mail-index-sync-update.c: line 730 (mail_index_sync_update_index): assertion failed: (view- >hdr.messages_count == map->hdr.messages_count)

file mail-index.c: line 415 (mail_index_map_parse_keywords): assertion failed: (ext->hdr_offset < map->hdr.header_size)

file mail-index.c: line 909 (mail_index_sync_from_transactions): assertion failed: (prev_seq <= max_seq && (prev_seq != max_seq || prev_offset <= max_offset))

file mail-transaction-log-view.c: line 158 (mail_transaction_log_view_set): assertion failed: (min_file_seq != max_file_seq || min_file_offset <= max_file_offset)

file mail-transaction-log-view.c: line 229 (mail_transaction_log_view_set): assertion failed: (view->cur_offset <= view->cur->sync_offset) file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos)



I wonder if anyone has experienced similar problems and if there is a solution to this strange behaviour.
