Segmentation fault & core file.

[Jayesh Shinde]

Hi ,

I am facing problem with randomly mail delivery to local mailboxes.  
While doing reconstruct its showing Segmentation fault
Also there lots of core.xxx files created under /var/lib/imap.

  -bash-4.1$  /usr/lib/cyrus-imapd/reconstruct -r -f 
user/amit.badarpur at domain.com
user/amit.badarpur at domain.com
Segmentation fault

And the dmesg is showing error like below .

imapd[7127]: segfault at 7f9092d7ce33 ip 00007f905fc1192e sp 
00007fff659f55e0 error 4 in imapd[7f905fbae000+191000]

I checked by moving the mailbox from iscsi partition to local drive and 
simlink the same .  But when i do reconstruct again it gives 
"Segmentation fault"
I checked by doing the gdb the core.xxx files , but not able to got the 
actual problem.

What could be the problem.  Is its related server's Memory  or currption 
on mailbox ?
How can I handle it.
