Hello all,
I'm getting a new crash issue on VMM service. This time this is not the DPM integration, this is not VMware integration, this is not SCOM Management Pack issue (yeah, all of these previously).
This time, I have a crash on Dynamic Optimization feature. One day, for unknown reason, vmm service started to crash constantly every 15min. After little investigation, this was everytime VMM run a dynamic optimization. I could find a workaround disabling dynamic optimization on my cluster praying for a new UR fixing this issue.
But this issue is annoying as this function is also used to evacuate VMs when getting host in maintenance-mode...Then I get this in debugview this error:

I have a VMM cluster, the same issue occures on each node.
Any idea about the source of this new crash ?
Best regards,
