@sjanc @andrzej-kaczmarek this looks like the same assertion that was attempted to be fixed by this PR: https://github.com/apache/mynewt-nimble/pull/748 . Any help in fixing this would be appreciated.

@lance-proxy thanks a lot. the problem seems to be triggered by ADV_EXT_IND received at the same time scan is disabled although I need to look through the code to figure out proper fix. could you please also dump `hdr` and `om->om_data[0]` parameters in frame 2 or 3?

I will keep the DUT trapped in the debugger in this state. Please let me know if there is any other globals you would like me instead while its in this state to help you root cause the issue here.

@lance-proxy I've seen this assert a few times when running qualification testcases but also was not able to catch it on a debugger. there was a bit of refactoring done in scanner so I guess I missed a corner case somewhere, but don't have clue so far. backtrace would definitely help a lot.

@sjanc @andrzej-kaczmarek this looks like the same assertion that was attempted to be fixed by this PR: https://github.com/apache/mynewt-nimble/pull/748 . Any help in fixing this would be appreciate.

@andrzej-kaczmarek no sign of this assertion after updating our test device fleet with `master` (including your PR fix above). Many thanks again for the quick turnaround fix on this! Im going to close this issue unless the issue re-appears.

Many thanks @andrzej-kaczmarek! I will load your PR on the same test device, and monitor if this assertion occurs or not.
