--------------------------------------

I have been plagued with timer issues for quite some time, removing the patch has moved the issue to a different place. Previous segfaults before this change were observed here:

The reported issue for this issue relates to a SIP retransmission, probably related to a reliable connection such as TCP/TLS. Is this correct?
