I just updated most of my hosts to BOINC 7.8.3, and noticed that as soon as I got a BURP task (on two different hosts), tasks from other projects that are suspended to let the BURP work go display the following status:

"Postponed: Waiting to acquire slot directory lock. Another instance may be running."

So far this, has happened on two hosts, although it seems after a while the status will change back to "Waiting to run". This even happens on NCI tasks like QuakeCatcher. So far, I've only noticed it happening while BURP is running, which is also the only multi-threaded app that has been running since the BOINC upgrade.

Is it anything to be concerned about?

Not entirely sure what that means - although it sounds like something is keeping files open in the slots directory when it shouldn't. What do you see in the task manager when this happens?

The apps marked "postponed" are still using CPU and memory.
