Hi,I have two WFE in my farm. I am seeing a large number of errors in the ULS for just one of them:2psl unexpected : "Unable to allocate an item in Perfmon Memory"We are coincidentally getting a number of reports from users that the system is not working correctly (custom controls and web parts not rendering) during roughly the same periods.I have googled the error but cannot find anything. Can anyone shed any light on this?TIAMarkMark

Hi, I have exactly the same problem. Did you find a solution to that issue? Thanks AlexAJ

Same error here. Anything new on this?

Did anyone got answer to this? I am also getting this error consistently and very frequently.
