Comment (by facundo.dominguez):

 I failed to reproduce the bug without redirecting with {{{-l}}}.

 I updated the attached eventlog and also the stderr output I get.
 Hopefully, they both sum up all the interesting information. Let me know
 if the split eventlog/stderr is still unhelpful.

 I'm using {{{labelThread tid "handleIncomingMessages"}}} to mark the dying
 thread.
