Percona-XtraDB-Cluster-56 crashed (CREATE statement)

[529]

I'm trying to run the plugin on Percona-XtraDB-Cluster-56 (3node) but unfortunatelly it crashes each time when I operate below.

I reported the following issue before, but the same problem has occurred in the "create" statement. https://github.com/mcafee/mysql-audit/issues/165

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Any help would be appreciated.

I need to reconfirm...

[529]

sorry.. It reproduced. Any help would be appreciated.

[aharonrobbins]

Thanks for the report. We don't officially support Percona. We will try to investigate, but I'm not sure when we'll have a fix.

Does this happen on a two-node cluster?

[aharonrobbins]

I misspoke in my previous comment. We do support Percona, but we don't automatically extract offsets for Percona releases.

In any case, knowing if this happens on a two-node cluster would be helpful. We will try to investigate.

Thanks.

[529]

thanks for your reply.

We do support Percona, but we don't automatically extract offsets for Percona releases. I understand. thanks!

this also happes on a two-node cluster.
