Phoenix miner process hangs, unable to kill,unable to reboot without hard reboot

[psypher246]

Hello all,

I have recently started mining and finding pools very unstable. I have been switching between 3-4 different pools but one of them inevitably gets DDOS'd and that kills my miner. Now this is ok I guess but the biggest problem is now this kills my phoneix miner and won't let it start up again on that pc. I can't kill -9 the process (with or without root) can't use top to kill it, nothing works. It's gone zombie. Now even bigger problem is that it locks the system up so badly that even a remote reboot does not actually reboot and it just locks be out completely. Can't ssh in yet i can still ping my PC. Only way to fix is a hard reboot. This is very annoying as I am not near the machine most of the day and now hours and power has been wasted which could have been spent on mining. Does anyone else have this issue and have a simple work around for it?

I would preferably stick to phoenix miner and would like to solve the problem with IT.

I am running on ubuntu 11.04 with the latest phoenix miner and ATI drivers

Also how long does it take till I can post in the proper forum groups?

Thanks

I don't have that issue but if it's only one pool that's doing it, why not just stop using that pool?  You said you have at least 3 others anyway.

No they all inevitably get DDOS'd at some stage, if I switch to a new one at eventually it stops working as well with "miner idle" error and then the process crashes

I've only seen that happen when the GPU itself is locked up.

The phoenix process cannot be killed, because it can no longer talk to the GPU.

Are you overclocking?  The GPU locking up is basically instability due to overclocking.  You may be *right* on the edge of what the card can handle, so when anything "strange" happens, it locks up.

Try backing the GPU down 5-10 MHz and see if it stabilizes.  Have you noticed it always happening to the same device?  e.g. Device 0's phoenix miner is always the one stuck?

Yeah I actually had a feeling this might be the reason so i have already started doing that. Scaled back 10 mhz. Yes it's one card mostly.

Suppose this error is a give away:

Kernel error: Unusual behavior from OpenCL. Hardware problem?

Just popped up So should probably scale down some more.
