    I have a bunch of Raspberry Pi's. As of this week they are having problems getting BRP4 work. The server status page said there are 41,000 tasks available to send. In this case it was running a single BRP4 task and the other 3 cores are idle. I have other Pis with idle cores unable to get work.

      I am new to E@H and have 2 Raspberry Pi's, a 3B and a new 4B.  Both of them are seeing the same problem as described above.  I would like to know if anyone has any information on this problem and/or how to correct the situation.

      Any help would be greatly appreciated,

      Tom

        Its a server-side issue so there is nothing us mere mortals can do.

        Having said that the Ready to send figure on the server status page has now dropped to 16,109 so its been giving work units to somebody.

          Thank's for the PM, I'm looking into it. May take a day, though, Raspberry Pi isn't our highest priority.

              Thanks Bernd. Ready to send is down to 8,000 but it seems to have stabilized now, work requests are getting filled again.
