> When using IMAP storage for Voicemail, I can reliably cause Asterisk to segfault. I noticed a number of random segfaults over the past few days and on further investigation, was able to reproduce it by running "voicemail show users for default". That produces the following segfault:
> {quote}Aug  8 07:50:10 timmy kernel: [1025781.678733] asterisk[20482]: segfault at 10d ip 00007fe97c22ab78 sp 00007fe8a0d09900 error 4 in libc-client.so.2007e.0[7fe97c1fb000+101000]{quote}
> This happens on multiple boxes so I've ruled out memory corruption or some other nastiness.
> voicemail.conf is at defaults except for:
> {quote}imapserver=mail.mydomain.com
> imapport=993
> imapgreetings=yes
> greetingsfolder=INBOX.Voicemail
> imapparentfolder=INBOX.
> imapfolder=INBOX.Voicemail
> imapflags=ssl
> [default]
> 0400000000 => 0400000000,Some User,,,attach=yes|imapuser=user at mydomain.com|imappassword=PASSWORD
> {quote}
> The relevant INBOX.Voicemail IMAP folder has about 300 voicemails in it. I think this may be related to users having forwarded messages out of those folders resulting in additional IMAP flags being added - though I can't be sure.
