Running zentyal 5.0 server which had frozen/hung and after that it does not start 3 services - redis-server, bind9, ntp.
I am able to manually start bind9 and ntp but redis-server fails to start.
In syslog file, notice following line:
Mar 3 14:09:08 alndc03 systemd[1]: redis-server.service: Main process exited, code=killed, status=11/SEGV
Following is from log file which asked to create a bug report.

Hey @shahdivy, this is an old report from a very old version of Redis. You probably tried to load a corrupt RDB file or one created with a newer version. Please feel free to re-open with more details if this reproduces with recent versions of Redis.
