After upgrade to 9.02 - VM backups failing

I upgraded from 7.03 to 9.02 and since then, I'd had a lot of funky issues, in particular, VM backups.

A lot of VM backup jobs have been failing, with errors like:

Read Error. Retrying to read from disk 'scsi0:1' for the 4 time...

then

Aborting connection to BSM. Abort code -1.

followed by

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

[61:3003]  	Lost connection to OB2BAR Backup DA named "ERROR"

I also have a handful of ESXi (5.1) hosts disconnect from vCenter (5.5) temporarily, which never happened during 7.x backups. 

Another nice bug is vepa_bar.exe taking up all system memory on the VEagent media server. That has happened a few times already from a backup job that backs up the VM's but doesn't finish.

Other notes include GUID folders remaining in C:\ProgramData\OmniBack\tmp and snapshots present on VM's, so cleanup is not done properly.

I have an active case open with HP but I may have better luck on the forum.  It's slow going...
