The crash might be related to a crash of osmo-msc: https://osmocom.org/issues/4160

Actions #2

Updated by dexter over 4 years ago

Apparently the crash can be provoked when osmo-msc is terminated and a call to an MS is made via sip landline. Then osmo-sip-connector should crash.

I have investigated this and I found out that close_connection() does call osmo_fd_unregister(). For some reason the osmo-fd is not registered in this special case. Lets check using osmo_fd_is_registered() before we unregister the fd.
