------------------
Can't make debug logs, 'cause attack start at random time, and if wait
this- size of debug log file- very big(don't have terabytes of disk
spaces)
Problem exist at 0.2.7.2-alpha, too exist at 0.2.6 branches.
If move hidden service to another server and OS(and another hosting
company)- problem absolutely same.
Hidden service work, after few time - 10-20-30-60 minutes- many records in
logs like I write earlier at top of ticket. Hidden service not available.
TOR process give near 10% of CPU (in normal work - 2-3%)
