             Summary: Crash when IMAP voicemail count reaches a high number of messages +250
                 Key: ASTERISK-23759
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23759
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_voicemail/IMAP
    Affects Versions: SVN, 12.4.0
         Environment: SVN URL: http://svn.asterisk.org/svn/asterisk/branches/12
Revision: 414209

CentOS release 6.4 (Final)

            Reporter: Alejandro Rios P.
            Severity: Critical
         Attachments: full-backtrace-ASTERISK-23759

An Asterisk setup with IMAP works ok with the default value of "maxmsg=400" on voicemail.conf

However, if I increase that value to a higher limit (maxmsg=400, for example), Asterisk crashes when reaching a voicemail count of about 250 to 280 messages (see the core dump and backtrace below)

I have reproduced this issue with different asterisk versions (1.6.2.20, 12.0.0 and the latest asterisk 12 branch from SVN)

**Message count for the test mailbox:
# grep X-Asterisk-VM-Message-Num /home/imap_user/mail/19779362020 | tail -n 1
X-Asterisk-VM-Message-Num: 257


**Backtrace:
