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.

Now that looks familiar. (See previous post of mine.)
