By: Richard Mudgett (rmudgett) 2017-09-13 19:06:31.886-0500 Threads 73 and 74 appear to be deadlocked in bridge_p2p_rtp_write() trying to get the AST_RTP_PROPERTY_ASYMMETRIC_CODEC property of the bridged peer rtp instance. AST_RTP_PROPERTY_ASYMMETRIC_CODEC doesn't exist on the reported 14.6.1 and the line numbers do not match inside res_rtp_asterisk.c. By: Joshua Elson (joshelson) 2017-09-13 19:20:25.737-0500 You are correct. Doh. Didn't realize we'd taken this patch. We applied this, it appears: https://gerrit.asterisk.org/#/c/6186/ Double checking to see if we're on the exact patch that was merged. By: Joshua Elson (joshelson) 2017-09-13 19:24:27.143-0500 This patch was updated because of this known deadlock issue. My apologies. We'll update on our end. |
