[Xymon] xymonnet crashing after upgrade to 4.3.15

[Gavin Stone-Tolcher]

Just reporting that I too have seen 1 x core dump from xymonnet on our test xymon setup since upgrading to 4.3.15 on Monday. Relevant gdb output follows:

[xymon at aztec server]$ gdb bin/xymonnet tmp/core.30031
GNU gdb (GDB) Red Hat Enterprise Linux (7.2-60.el6_4.1)
....
....
Core was generated by `xymonnet --report --ping --ping-tasks=5 --test-untagged --concurrency=64 --cont'.
Program terminated with signal 6, Aborted.
....

I have also applied the supplied patch and will report any issues.

Ok, I have applied it on one of our machines. I'll wait and see if it makes any difference. The crashes are not too frequent, it has happened 3-4 times on either server after the upgrade.
