Hi, I still get this sometimes with bfgminer-2.10.5 (openwrt) and p2pool (terracoin ).
In my case, bfgminer gets into this if freshly started and immediately gets a stratum work restart.
(edit):
Messages: Debug "Work stale due to block mismatch (f59904bd != 0 ? f59904bd : ff606682)"
And normal output only "Stratum from pool 0 requested work restart"

This also happens sometimes when switching to a new stratum pool.

More precisely: Debug "Work stale due to block mismatch (f59904bd != 0 ? f59904bd : ff606682)"
And normal output only "Stratum from pool 0 requested work restart"

This also happens sometimes when switching to a new stratum pool.

This has become an increasingly common occurrence for me. To make matters worse any restarts or pool switches after it hangs in wait restarts it in the same condition. Let one worker go for over 5 hours the other day and never recovered.

This bug is fixed. Your issue has nothing to do with it as far as I can see.
Open a new issue with full details of your problem.

You cand leave it closed, but I'll give here the solution, since this is the thread I found when faced with the problem.

I'm not sure if it's a bug, I can open one no problem if necessary.

Basically it happens because I mixed TRC + BTC pools in the pool options, while having strategy Failover but "Failover only" = not enabled (the default). In this mode the miner sends shares to different coin pools, and there is the conflict.

I can solve it by either disabling the other coin's pools or by using --failover-only.

Um, yeah... it's always been clearly noted in the README that BFGMiner does not support mining multiple blockchains at the same time.
