Hi,
My setup: Solaris 9, mbox format, mailboxes NFS mounted from
another S9 system, imap. I got the following assert yesterday:
Jan 30 19:57:15 emerald dovecot: [ID 107833 mail.error] imap(user):
file index-mail-headers.c: line 258 (index_mail_parse_header): assertion
failed: (part != NULL)
Jan 30 19:57:16 emerald dovecot: [ID 107833 mail.error] imap(user):
file index-mail-headers.c: line 258 (index_mail_parse_header): assertion
failed: (part != NULL)
The gdb work on the core file is attached. This is a mystery because
part was NULL in the core file. Weird.
