When i migrating Jenkins from master hyper-V host to secondary, CVS plug-in time to time (about 1x - 2x per day) stops working.
It seems to be, that connection was lost but plug-in waits infinitely for more data that never come.
Also cancel build doesn't work at this moment, only possible way is stop jenkins.
I using pserver, compression level 0 and CVSNT as CVS server.
