Hi List Regarding this Asterisk instance as discussed previously (Asterisk 1.8.11.0) that was consuming enormous amounts of file descriptors (100 000+ for about 50 simultaneous calls) it appears I have managed to solve my problem by upgrading the 1.8.11.0 Asterisk instance to an 1.8.32.3 Asterisk instance.
Also, the file descriptors apparently leaking were paired with timer problems in 1.8.11.0 whenever I went above about 50 concurrent calls on the box while running on 1.8.11.0. The thing is in our setup we have about 15 instances of 1.8.11.0 at the various branches of the company, all running 1.8.11.0, BUT at none of these sites do we ever exceed 40 simultaneous calls. The defining factor was (in our case, with our dialplan) to run 1.8.11.0 and try to run 50+ concurrent calls. What would happen was that thousands of these messages would come up in the CLI: [Aug 13 09:41:38] ERROR[25193]: res_timing_dahdi.c:89 dahdi_timer_set_rate: Failed to configure DAHDI timing fd for 0 sample timer ticks when we reached or exceeded 50 calls. The same happened whether pthread timing or kernel timerfd timing was used. Several other weird errors would manifest in the CLI, to whit: --- format_gsm.c:102 gsm_write: Bad write (32/33): Destination address required [Aug 12 12:23:33] WARNING[29436]: channel.c:1474 __ast_queue_frame: Exceptionally long voice queue length queuing to Local/number@local-3E1C;1 WARNING[8210]: res_rtp_asterisk.c:1773 ast_rtcp_read: RTCP Read error: Bad file descriptor. Hanging up. [Aug 12 09:56:55] WARNING[29931]: file.c:198 ast_writestream: Translated frame write failed --- when we were spamming the timer errors. Practical effects were dropped calls, calls with bad quality / what sounds like severe jitter, and mixmonitor recording files that were not written or corrupt. The solution (so far, still checking) was simply to upgrade to 1.8.32.0 and most of our problems disappeared, for us in our setup, with our dialplans. The upgrade was painless, since we stayed in the 1.8 range, we did not have to modify any of our config files or dialplans. Maybe this can assist someone else struggling with older 1.8 series timer issues.
