> In my setup of two inter-connected routers, several senders connecting to one router
while few receivers connecting to the other router, I see several crashes in the router to
which senders connect.  These crashes are intermittent and happen once in every 10 runs or
so.  I have collected the backtraces of all the crashes but do not yet have a test case that
can reliably reproduce any of them.
