Have an Asterisk PBX (phone system) that stores the voice mail in IMAP with
libc-client. Concurrent access to voicemail, not the same mail box is
crashing the system. Any ideas what might cause a back trace like this?
Notice there are always to threads involved when there is a segfault but
cannot piece together why. Thanks! (sorry if this is posted twice sent
original before subscription confirmation)
