I was mining at US-Eligius and it went down. But the miner just spammed this:

[6/8/11 2:13:51 PM] Rejected block 1075 found on Cayman (#2)
[6/8/11 2:13:51 PM] ERROR: Connection failed: connect timed out

It kept working for 30 minutes, every found block was labeled as rejected and connection failed spam. I had a backup miner pointed at BTC-Guild, but it was still working with minimum of 2Mh/s, the miner pointed to Eligius was still working at full load(692Mh/s). I had to manually shut it down for the backup to kick in.

Is this a problem with DiabloMiner or with the pool giving 30+ minutes worth of work? :)
