I am having a similar problem. I am not yet convinced that it is SER
as much as my configuration but if SER does have difficulty processing
CANCEL messages it would be helpful to understand under what
circumstances.
By the way I have been using t_check_status in a similar way since
v 0.8 code. When I upgraded to 0.9.0, .0 and now .2 the t_check_status
fails to be matched.

Thanks,Steve
