is the version you are using linked to json-c or libfastjson?
we know there were thread-safe problems as a result of json-c David Lang On Thu, 12 Jan 2017, Christopher Racky via rsyslog wrote:

While 8.16 works fine, all following versions, including 8.24 which was released a few days ago leads to problems that results in core-dumps: rsyslogd[1408]: segfault at 7f9f2910b9d0 ip 00007f9f2e18e213 sp 00007ffd3d9fe080 error 4 in libpthread-2.12.so[7f9f2e186000+17000] rsyslogd[4201]: segfault at 7f991c0789d0 ip 00007f99210fb213 sp 00007ffec5155240 error 4 in libpthread-2.12.so[7f99210f3000+17000] rsyslogd[2783]: segfault at 7f5f695399d0 ip 00007f5f6e5bd213 sp 00007ffe4b4da5c0 error 4 in libpthread-2.12.so[7f5f6e5b5000+17000] rsyslogd[6816]: segfault at 7f519ad269d0 ip 00007f519fdaa213 sp 00007ffd22bf2470 error 4 in libpthread-2.12.so[7f519fda2000+17000] My hope was that this topic was solved by https://github.com/rsyslog/rsyslog/pull/1274 But it was not. As problems seems not (directly) related to lookup-table, I guess it also has a problem with thread handling. https://github.com/rsyslog/rsyslog/issues/1071 Do you have any further idea? With single-thread mode problem does not appear and also in lab, I was not able to reproduce it. But on several production servers the issue occures quite often. regards Chris _______________________________________________ rsyslog mailing list http://lists.adiscon.net/mailman/listinfo/rsyslog http://www.rsyslog.com/professional-services/ What's up with rsyslog?
