Now both my machines are sticking on downloading WU's. Even a restart of the client will not fix them. Anyone else having this problem?

kqpahv mentioned this error on the previous page but restarting the client did reset his.
You're welcome
Now only thing I am checking is GPU utilization and if thats 95+% I dont care about the numbers that the client is showing anymore.
I'v got a different problem myself now: Some GPU's get stuck downloading new WU's

Stays on "downloading" forever with no getwork server address available. Restarting the client solves this but is really uncomfortable if you have many rigs to keep an eye on....
This started yesterday, anyone experiencing the same thing ?
Check the log and see if you are getting the same error message he got. So far I have not run into this error but I am watching for it.
I am getting "05:32:12:ERROR:WU00:FS00:Exception: Server did not assign work unit". 2 out of 4 card on one machine, and 2 out of 3 on the other. Rebooting them didn't even fix it.
