ah okay, I missed that this was found using openmpi.

then it’s probably not the same issue we had.

I can’t remember in which version it was fixed (I’m away from my work computer)….I do know in our case openmpi and the latest Intel One API work fine.

Same if I add a counter or print statements before and after EventBegin/End. Looks like a memory corruption problem, maybe nothing to do with petsc despite the error message.
