[Dovecot] 1.0alpha1: new assert/core

Hi,
I saw a new assert and core dump today in 1.0alpha1.
Setup is Solaris 9, dovecot built with gcc 4.0.1, running
as imap server for mbox format. The syslog said:
IMAP(user): file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos)
A gdb analysis of the core dump is attached. BTW, I save
core dumps in case you need further debugging done for an
assert.
On another note, I have also had issues with dovecot locking
up with "Too many open files" syslog error messages. Last night,
after several hours of "too many open files" complaints, the
master dovecot process just died -- no core dump and no complaint
to syslog. Per advice of the list, I have doubled the rlim_fd_cur
and rlim_fd_max kernel parameters and rebooted my imap server.
I also saw in my syslog:
Sep 6 16:48:53 emerald dovecot: [ID 956436 mail.error] pipe() failed: Too many open files
Sep 6 16:48:53 emerald dovecot: [ID 257797 mail.crit] dup2(stderr) failed: Bad file number
With students back, they have been giving dovecot a real hard
workout.
