CMS plan to switch over the ETF tests from the pre-prod this week:

• ETF pre-production was updated with latest HTCondor client and patches undone one by one; everything looks good;
• issue with the /Role=production proxy discovered last week in EL9 instances
• will give us stable job submission to ARC-CEs; old worker node tests will stay production; switch to new worker node tests next/in a few weeks?"

Spotted again that 'running cores' did not match between CMS and RAL monitoring - operator checking FNAL schedulers again, but looks better today. 

'500' transfer errors reported by Brij also seen by CMS at RAL, but not only at RAL. It may be this is quite a generic error but it is seen at several other sites. It's mentioned in this ticket with FTS: https://cern.service-now.com/service-portal?id=ticket&table=incident&n=INC4460338

The mystery of failing 'mc' SAM tests due to stageout error 2 weeks ago - this coincided with downtime of RALPP storage. RALPP is our fallback site for stage out. The problem was that the test was always failing to stage out to Echo because the port was missing in the config. This is now corrected. Production jobs were never affected.
