Hi ALL,

When i was accessing the voice message it suddenly goes dead and after that
i couldn't able to retrieve the voicemessage again from my mailbox . This
happens once in a while for any configured mailboxes

I am using the following system configuration.

asterisk 1.4.22.1
odbc storage of voicemail messages
centos 5.2 64bit
unixODBC-2.2.11-7.1
mysql-connector-odbc-3.51.12-2.2
mysql-server-5.0.45-7.el5

Following are the traces i found while troubleshooting the issue.

1) I found a .lock file created in the INBOX folder of my mailbox
2) The following core dump gets created during the first time the
voicemessage access got failed.
