With sup-miner  get the following error:


[2015-02-22 07:49:36] Starting Stratum on stratum+tcp://sup.suprnova.cc:7777
[2015-02-22 07:49:36] 7 miner threads started, using 'pluck' algorithm.
[2015-02-22 07:49:36] workio thread dead, exiting.


wolf-pluckminer-generic64-update1 with the SAME options is operating normally

try on Win 7 x64 and Win Server 2008 x 64 at different hardware

what ideas?
