[Gluster-devel] glusterfsd core on NetBSD (https://build.gluster.org/job/rackspace-netbsd7-regression-triggered/14139/consoleFull)

[Kotresh Hiremath Ravishankar]

The crash reported on the above link is same as bug 1221629.
But stack trace mentioned below looks to be from different regression run?
Can I get the link for the same?

It is strange the bt says 'rpcsvc_record_build_header' calling 'gf_history_changelog'
which does not! Am I missing something?

Thanks and Regards,
Kotresh H R
