FYI when using stratum proxy
2012-11-27 21:57:58,967 INFO proxy jobs.extranonce2_padding # Extranonce size mismatch. Please report this error to pool operator!
No problems when using getworks.
Same problem here. Ztex FPGA BTCMiner + slush stratum proxy 1.1.1.
I don't get this error using slush, ozcoin, btcguild or itzod.
