Getting "Exception flag set on 'Snoop'" Warning When Snoop on Channel

Asterisk Asterisk Support

Hi all,

I’m encountering the following warnings in the logs whenever I use the Snoop feature on a channel:

[Sep 29 17:03:59] WARNING[666283]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/1759134364.74160-00000002', but no exception handler[Sep 29 17:03:59] WARNING[978285]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/a6afae5f-5d69-45ca-b5d8-10b1442a5fca-00000011', but no exception handler[Sep 29 17:03:59] WARNING[811032]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/794f65cc-96c8-4d12-9817-172960379acd-00000006', but no exception handler[Sep 29 17:03:59] WARNING[990102]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/bfc52d63-f4d2-45ab-ab49-f461f5032a19-00000012', but no exception handler[Sep 29 17:03:59] WARNING[665929]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/17c1a992-21b1-43c5-8382-501eb16617d5-00000001', but no exception handler[Sep 29 17:03:59] WARNING[957259]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/1759143623.119452-0000000c', but no exception handler[Sep 29 17:03:59] WARNING[787780]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/1759137974.94507-00000004', but no exception handler[Sep 29 17:03:59] WARNING[809153]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/1759138293.96970-00000005', but no exception handler[Sep 29 17:03:59] WARNING[811032]: channel.c:3750 __ast_read: Exception flag set on 'Snoop/794f65cc-96c8-4d12-9817-172960379acd-00000006', but no exception handler

Upon investigation, I found that this issue only occurs when using res_timing_dahdi.so. There are no issues when using res_timing_timerfd.so.

Please help me figure out the cause and possible solutions.

The dahdi timing module is seldom used, so it may very well have not been tested with Snoop channels and they require an additional callback to be added. As for solutions - there isn’t one aside from investigating and making any code changes required. Does the Snoop channel fail to work?

Actually, the Snoop channel doesn’t work -there’s no voice from the Asterisk side when using res_timing_dahdi.so.

Then I’d suggest filing an issue[1].
