[Dovecot] file-buffer_offset + file-buffer-used == file-sync_offset
I got the following panic on 1.2.3: Panic: file mail-transaction-log-append.c: line 88 (log_buffer_move_to_memory): assertion failed: (file-buffer_offset + file-buffer-used == file-sync_offset) It's probably related to the file system holding the indexes being full.

[Dovecot] high imap load on large folders
Hello,
i sync with imapsync from an archiopteryx-server to an dovecot-server, for
testing until now.
The dovecot is inside an VM. storage for mail is on an nfs-share, indexes
are local.
What i now see, is, on large folder( 58000 messages and more) the load
on the imap-process
is very high, and slowdown the transferprocess.
Is there something, I can do. Whats cause the high load ind the
imap-process.
Here are the configuration, and below, a partial strace
