Description:	On high load servers, when the CLI starts flooding messages, the other end will get timeout for sure. There should probably be a limit on the calls going through one trunk, or the trunk_max_data_size should auto increase. ****** ADDITIONAL INFORMATION ****** Just an example, if you do too many simultaneous trunked calls, suddenly the CLI will start flooding with: Sep 15 11:38:12 WARNING[348499]: chan_iax2.c:2919 iax2_trunk_queue: Maximum trunk data space exceeded to 10.5.0.7:4569 flood will result in: After a few seconds, the other end of the link will get something like this. Sep 15 11:38:05 WARNING[12300]: chan_iax2.c:1466 attempt_transmit: Max retries exceeded to host 10.3.3.6 on IAX2/guest/16849 (type = 6, subclass = 2, ts=220016, seqno=64) And the calls will get dropped. Its not just a problem with this out of frame data, every time the cli decides to flood, calls WILL get dropped. (or at least the audio will have drops).
Comments:	By: zoa (zoa) 2004-09-15 03:43:51 Please note that this is only for very high load.. (as in > 500 simultaneous calls). By: zoa (zoa) 2004-09-15 03:46:16 This situation also doesn't self heal, once it happened, it keeps flooding. For example, i currently have not a single call between my two trunked servers and no new ones are being made, but its still flooding the cli on one end. (already for 10 minutes). By: Mark Spencer (markster) 2004-09-17 08:36:45 Max trunk data is currently hard set to 200-400 channels in chan_iax2.c, have you tried adjusting MAX_TRUNKDATA in that file?  Thanks. By: zoa (zoa) 2004-09-17 11:51:57 no, i didnt yet. (probably post astricon). This is more a request than a bug report, so i changed the title.
