After the recent outage, I just tried a project update to report results and get new work and received the following:

6/11/2007 5:57:28 AM|lhcathome|Fetching scheduler list
6/11/2007 5:57:33 AM|lhcathome|Master file download succeeded
6/11/2007 5:57:38 AM|lhcathome|Sending scheduler request: Requested by user. Requesting 28700 seconds of work, reporting 7 completed tasks
6/11/2007 5:57:53 AM|lhcathome|Scheduler request succeeded: got 0 new tasks
6/11/2007 5:57:53 AM|lhcathome|Message from server: Project encountered internal error: shared memory

Problems?

Live long and BOINC!

From general discussion over at SETI@home, I've gathered it involves two (or more) "processes" trying to access a file at the same time (i.e. BOINC and an anti-virus scan). I don't know what it would be for Server Access...

That would be true on a normal computer, but from memory isn't the Shared Memory on a BOINC server the space where they keep all the results for various platforms?

There is a process on the server that loads some work from the database into the shared memory block. The scheduler starts whenever somebody asks for work, and it reads the data from the shared memory block (instead of going to the DB directly).
