** [tickets:#2182] mds: MDS receive thread may hang when a signal is caught**
**Status:** accepted
**Milestone:** 5.0.2
**Created:** Wed Nov 09, 2016 03:42 PM UTC by Anders Widell
**Last Updated:** Wed Nov 09, 2016 03:42 PM UTC
**Owner:** Anders Widell
The result from poll() is incorrectly stored in an unsigned integer, which
means that if poll() returns -1 we will interpret the result as a very large
number. Subsequently, we read the possibly undefined values of pollfd.revents,
and may perform a blocking read.
