Ahh I see... There was no other log info (at least no other unusual
info) before the exception occurs unfortunately. Just the standard IAR
loading procedural stuff then the exception(s) immediately after it is done.
Is it anything I should be concerned with as far as possible data
corruption or IAR assets/inventory objects not being loaded fully or
anything?
Thanks =)

An async_call_method thread is sometimes running through an

in this error. It's some kind of race condition since this doesn't
occur consistently.
This is a different problem from that seen in Mantis 5669.
It's very unfortunate that there's no other log information here (I'm
assuming that you're not missing anything out), since there's no
indication as to where in the code this is occurring. Finding it
might mean a forensic analysis of the code called by IAR loading, and
even then it could be triggered by other processes occurring in parallel.
The changes are this has been occurring some time and has only
recently been revealed by logging exceptions that come to the top of
async_call_method threads. We may have to comment this logging out
temporarily for the release.

Hi all. On latest master (r/16668) I've been getting some weird
exceptions after attempting to load
an IAR. Some times I'll get multiple errors, sometimes only a few or
one, or sometimes the exception
is not thrown. Doesn't seem to matter which avatar I attempt to load
to or how big the IAR is. What
could be causing this?
Thanks :)
