Description David Hill 2023-02-21 13:42:10 UTC

Description of problem:
ovn-controller core dumped and the corefile returns this:

Core was generated by `/usr/bin/ovn-controller --pidfile --log-file unix:/run/openvswitch/db.sock'.
Program terminated with signal SIGSEGV, Segmentation fault.

Do we have debuginfo for ovn ?  I couldn't find it but it crashed there on RHOSP16.1.9 -5

I have bumped the OVS submodule for ovn2.13. I have pushed the change and created a build for it as well. The build is ovn2.13-20.12.0-198.el8fdp .

I'm marking this issue as MODIFIED since this should be fixed now.

Comment 7 Mark Michelson 2023-03-30 14:48:27 UTC

I'm moving this back to ASSIGNED. The builds that I created yesterday all succeeded except for x86_64. It failed due to a crash in a test program. I have reproduced it locally and am debugging it. I'll update the issue back to MODIFIED and set the proper fixed-in version once I have the crash fixed. I suspect the crash is just in the test program and not due to anything wrong in OVN itself.

Comment 8 Mark Michelson 2023-03-30 19:48:31 UTC

I fixed the issues with the build. The fixed-in version is ovn2.13-20.12.0-201.el8fdp
