job hangs although failed after ConcurrentModificationException of ExwsAllocateActionImpl

      Description

      I have a pipeline Job that does some simple checks for all nodes every 5 minutes.
      Sometimes (something like twice a day) this job fails with ConcurrentModificationException in ExwsAllocateActionImpl (on a Windows node while accessing a file on the network). This has been happening ever since but I didn't bother because the next build ran fine again.

      But since some updates (in July or August) the build hangs in a strange state after this exception.
      Somehow the build is still running although it is failed already.
      Therefore the next build doesn't run because it waits for the previous build to finish (I configured to not allow concurrent builds).
      I can't abort the failed build because it is already failed.
      So I have to delete the failed build in order to get the next build running.

      It doesn't happen anymore since I switched "Pipeline speed/durability override" from
      performance optimized to maximum durability

      Log:
