We shipped Data Source Service Pack for for OCI 7.3.[1-4] last week. As always, you should install the latest service pack to keep your data source code up to date.
There are not a ton of new features in SP4, but it does add NetApp SolidFire volume to volume replication relationship support. We promoted a few datasources out of "beta" status
Edit: We had to make a subtle naming change as the original SP4 was built in a way that would not allow for installation on OCI 7.3.4. "SP04" is the same content, but built to be applicable to OCI 7.3.[1-4]. The URL below has been updated accordingly.
Thanks for calling that out - we had to re-post SP4 as SP04 due to a hiccup in our process. The original SP4 wasn't installable onto OCI 7.3.4, and it should have been. SP04 is named as such because apparently the support website doesn't allow for replacements.
That is extremely surprising - there are not any fixes related to VMware performance in SP4 for anyone that has SP3 installed. The only VMware changes in SP4 are
A workaround for EMC ScaleIO (ScaleIO is a proprietary storage platform whose client software on ESX introduces fake FC HBAs whose WWNs are not very unique. In large VMware environments, one can have duplicative fake WWNs, which OCI's datasource used to detect and fail on). OCI now pretends these fake ScaleIO HBAs do not exist.
And a minor supportability improvement where we are logging the vSphere build number so we can quickly understand against which vSphere release+update a given datasource is talking to.
We do not support uninstalling Service Packs - if a Service Pack introduces a problem, we will need to fix it with a patch.
I have looked over what you have uploaded with the case, and it is extremly odd - OCI defaults to having 4 worker threads per Vmware performance poll, so the group0-3 messages relate to each of those worker threads. It looks like OCI's VMware datasource is throwing a null pointer exception on each of those 4, and this seems very consistent across the periodic performance polls this datasource is making.
I have opened an engineering issue on this for you
