[SR-Users] event on table location Duplicate entry for key 'ruid_idx'

[Daniel-Constantin Mierla]

Would be interesting to discover the issue that got here. server_id can
help in the future, but the chance of getting overlapping unique ids is
very low even with it. That's why I asked for 'kamctl ps' to see if
there are PIDs overlapping on the two systems. Then it is also the start
time that matters, so should be started in the same second.

On the other hand, the error can be from same system or maybe it happens
after a restart when both load the records from db or something else ...
so figuring out the cause will rule out there is no issue, I would still
want the details I asked for.

Cheers,
Daniel
