Miners, please try using: --queue 0 --scan-time 5 --expiry 10
I have noticed an increase in DOA's which causes connectivity problems with the wallet.
http://csc.xpool.net:8840/ currently has 82.2 Mh/s out of the CSC p2pools 91.3 Mh/s. If there are any other public nodes please post so we can distribute the load.
Also, with such a large hash rate at the pool it is important that you set the worker difficulty for your miners.
To set the difficulty for your specific hash rate multiply by 0.00000116
For example, if your miner is capable of 1440 Kh/s:
1440 * 0.00000116 = 0.0016704
Example Connection String for a miner capable of 1440 Kh/s:
cgminer -o stratum+tcp://csc.xpool.net:8840 -u CJbGVMDmqWWptWTcwRU2bzNg8auMzoUenJ
+0.0016704 -p password --scrypt --queue 0 --scan-time 5 --expiry 10
Miners, please make sure you're correctly setting your difficulty. This is super important to curb the amount of DOA and orphans within the pool. It's pretty easy to calculate.
