Timeslot reservation errors%3A %22Insufficient resources%22 show only at run time

We're running PC 12.62.  We have an 'A' pool of LG's/Ctrl and a 'B' pool.  We've used PC since 11.52 and have never seen this before.   When running tests using the A pool, we can successfully schedule a run of tests sharing the same time period for tests running 'B' pool.   But at run time, the scheduler will indicate a run time failure because we have insufficient resources. The system will try and try to run with new run instances, until it gives up.  (Attached a screenshot to see what it looks like).  Obviously, I bring this up, because we're using separate resources, so this shouldn't happen.  We brought this up with tech support, and they are telling us this happens because our tests are using parameters set to 'Unique'.  We've run tests for years using this parameter setting, and that makes zero sense.  Also, the problem doesn't show up all the time.  

Anyone else ever see this?  Wondering what you did to resolve.  Thanks!

Hi, 

Based on the screenshot seems that the required specific LGs (perflgb1 etc.) were non operational therefore no available resources. 

Please check in the relevant LGs event log if indeed the LGs were non operational for the relevant timeslot , if yes - that's explain the behaviour.

Re: Timeslot reservation errors%3A %22Insufficient resources%22 show only at run time

Thanks for your response.  Is there a specific way to tell if a resource was operational at the moment it was called?  We're troubleshooting, so there were no other tests running at the time.  The machines were listed as operational before and after, but looking at things like 'Event Log' tells me that the statuses were constantly being changed (3 times) before the rest finally ran.   Usually if a machine is non-operational, you have to manually flip it back to operational when there's been a problem right?  I haven't had to do it.  Everything is all green.

Hi,  

The event log is the best to track it for the history,

None operational  hosts will move to operational as part of the Check Host Task.

Check Host Task

Verifies the host installation, and updates the host status to either Operational or Non-Operational.

Default frequency: Every 15 minutes

Re: Timeslot reservation errors%3A %22Insufficient resources%22 show only at run time

Hi Aliza,

I was out of commission for a few days, but did want to follow up with you.  I've attached an eventlog screen capture.  The test we had set to run was for 3/2 at 4:30 PM.  We can recreate this issue every time, where the resources ARE up, but when the conflict shows up, we get three status changes on the host and a recovery task run.  All the resources look like this whenever we make this scenario happen.  

We do believe now that this has to do with the tests running 'Unique' parameters and that the test setup process to distribute these parameters across the LG's is related to these failures.  Not sure where to look to get more evidence of this.  Do you have any suggestions?

Hi Meh, 

Seems that this issue requires further  debug. As you already have an open support case , please ask to elevate it to R&D for review.

Thanks
