--- Comment #22 from Ben Werthmann <ben at apcera.com> ---
Running this command before peer probe reproduces this problem (leading to the
backtrace handler problem) in all cases:

sysctl net.ipv4.ip_local_reserved_ports="49152-49156"

or

sysctl net.ipv4.ip_local_reserved_ports="24007-24008,32765-32768,49152-49156"

The issue appears to be with parsing the contents of
'/proc/sys/net/ipv4/ip_local_reserved_ports' here:

https://github.com/gluster/glusterfs/blob/master/libglusterfs/src/common-utils.c#L3038

This option appears to defer to the kernel for source port selection. Is there
a known issue with kernel port selection?

https://github.com/gluster/glusterfs/blob/master/configure.ac#L312-L320

I'm going to build and test with the above configure option.
