Hi Chavdar and Michael,

Thanks for your thoughts and help.

I added "memoryefficientbackup". 

But still the sessions keep crashing. Once the session crashes, I get a whole 
bit of errors   for storage pool directories, and in fact the whole pool 
becomes unavailable. 
I run "update stgpooldir ... access=readwrite" and all is accessible again.
Some of the containers are in unavailable state and need audit. 

Our container storage is on a Dell PowerEdge R730xd, has 24 CPU's allocated, 64 
GB memory, 110 TB disk.  The disks are declared as VMDKs.  Network is on a 10Gb 
Intel 82588 card.
Nothing I can see points to a lack of resources.

Everything worked fine till 4 days ago. That is why I thought of a problem with 
Windows updates, but as I rolled them back, that does not make sense.

I am quite at a loss where to look next ...

Thanks

David

Just to make sure that we are on the same page...
You have TSM installed on VM running on VMware. This VM has few LUNs presented 
and those LUN are used for containers?

Short in the dark:
1. Check VM resources if they are as IBM TSM blue print.
2. Check LUNs/HDDs response time in perf. monitor. The response time should 
around 20-30 Ms during the backup operating.
3. Do you know if those HDDd for LUNs are .vmdk or RDM (raw device map)?

Thank you!
Chavdar
