Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: modules Group: 1.7.x Status: Open Resolution: None Priority: 5 Private: No Submitted By: Muhammad Shahzad (shari_786pk) Assigned to: Bogdan-Andrei Iancu (bogdan_iancu) Summary: sigfault in presence module due mix_dialog_presence flag Initial Comment: Enabling "mix_dialog_presence=1" in presence module causes random crash. Core dump of each crash shows sigfault that happens only when using a specific version of Eyebeam. So, it may be a bug in Eyebeam instead of opensips. Anyhow, here is the BT. Core was generated by `/usr/local/sbin/opensips -P /var/run/opensips.pid -m 512 -u root -g root'.

If its eyebeam version then i can simply block its user-agent in opensips dial plan to avoid crash. Let me try to contact the end-user who has this eyebeam version and see s/he is willing to help us out in reproducing this crash. Thank you. ---------------------------------------------------------------------- Comment By: Bogdan-Andrei Iancu (bogdan_iancu) Date: 2011-09-02 00:37 Message: Just to know in what direction to go with the troubleshooting - can you reproduce this crash?
