my username is USER401

I'm in richmond Virginia right now, on 34/34 mbps fiber.. shouldn't be having any latency problems.. I'm using phoenix obviously... though currently my mining speed is fairly low (have a better card arriving tomorrow)

edit 1:though running today, i seem to be doing 'ok' i finally got a long poll, wasn't getting them before I dont think. So I got 2 accepted and 1 rejected then an LP: New Work Pushed.

edit 2: or maybe not... the next result after the LP was rejected :| I'll let it run for an hour or two and we can see where it gets to.

edit 3: ok i think that is enough mining...

That are way too much stales. Are you using EU01 or US01?

connected, we shall see.

edit: No bueno. Seems to have even less results too.. getting multiple LP between results.

The multiple Long Polls are due to the fact that at the moment we see a really large influx of hashing power on namecoin blockchain. Thus we are far away from one block per 10 mins. Furthermore a merged mining pool sends LPs each time a block is found on either of its blockchains. This is definitely a drawback, but there is no other possibility.

However I'm wondering about your frequent rejects. Could you please tell me which timezone your timestamps are? I want to verify if your client catched all LP which had been sent from MasterPool. Perhaps this is an issue with slower cards or with phoenix version. I'm still using 1.5 and have no issues but I have much faster cards. Would you mind trying with poclbm?

Is there anybody else out there having this problem?

as i said, i'm in virginia.. same timezone as your US server.
Now I just got a 6790, going to see how that works for this.

edit: alright, with the new card, i'm getting pure accepteds... maybe it was just cause my card was slow? but... that is odd.

With the recent amount of new users the pool faced a massive problem with high stales and was responding very slowly. I analyzed the problem and found out, that the database is the bottleneck. I prepared a solution but it means a major downtime for the pool. In order to circumvent the bottleneck I need to split some tables. This however took about 30 minutes on the testing mashine. I guess it'll be the same for the production database cluster (perhaps a bit more, as they are synchronizing themselves). In order to get the pool back on track. I'd like to roll out this update very soon and apologize for this short announcement. But as the pool sometimes stops responding for some seconds anyway I guess it's better to address this ASAP.

I'll start with the rollout at 8 pm UTC.

You may want to switch your miners to another pool for this time or make sure you have configured a failover pool.
