Hi, We are using a Sangoma board in a conference application.  Sometimes, the outbound audio stream is very choppy. Recordings from with mod_conference are fine, so we think there is a problem with the outbound writes to theSangoma board.  I made a recording using the wan_ec_client tool, and I can definitely hear choppy audio comingin to the Sangoma board, from the FS side (the Rin is choppy). I see these FS logs, near the time that the problem occurred:2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c1][1:1] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c2][1:2] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c3][1:3] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c4][1:4] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c5][1:5] Rx Queue length exceeded 80% threshold (9/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c6][1:6] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c7][1:7] Rx Queue length exceeded 80% threshold (9/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c8][1:8] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c9][1:9] Rx Queue length exceeded 80% threshold (9/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c10][1:10] Rx Queue length exceeded 80% threshold (9/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c11][1:11] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c12][1:12] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c13][1:13] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c14][1:14] Rx Queue length exceeded 80% threshold (9/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c15][1:15] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c16][1:16] Rx Queue length exceeded 80% threshold (9/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c17][1:17] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c18][1:18] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c19][1:19] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c20][1:20] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c21][1:21] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c22][1:22] Rx Queue length exceeded 80% threshold (8/10) 2016-09-16 09:25:45.126458 [DEBUG] ftmod_wanpipe.c:982 [s1c23][1:23] Rx Queue length exceeded 80% threshold (8/10) We are using FS version 1.5.13b.  Any ideas what could be the problem?
