Andrey Gura commented on IGNITE-10482:
--------------------------------------
{{FaiureProcessor}} dumps all stacks. This behaviour is switched off on TC in
order to avoid tool large logs. See
{{FailureProcessor#IGNITE_DUMP_THREADS_ON_FAILURE}} for more details.
> Print stacktrace of the blocked thread in failure handler.

> URL: https://issues.apache.org/jira/browse/IGNITE-10482
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Reporter: Roman Kondakov
> Priority: Major
> Labels: iep-14

> If a blocked thread is detected by the error handler, only a detector's
> thread is printed to the log. But it is much more informative to print a
> stacktrace of the blocked thread.
> As shown below, {{disco-event-worker}} thread has detected blocked
> {{sys-stripe-0}} thread. But stacktrace of {{sys-stripe-0}} is not printed
> despite the fact it is of particular interest.
