Hi,
An assertion that I haven't seen before:
Apr 20 11:15:32 emerald dovecot: [ID 107833 mail.error] IMAP(user): file
mbox-sync-rewrite.c: line 106 (mbox_sync_headers_add_space): assertion
failed: (start_pos < data_size)
gdb output from the core file of imap is attached. My setup:
Solaris 9, mbox format, INBOX is NFS mounted from a Solaris 10
system, imap and imaps only.
