Hi !
I've installed Synchronet 3.18 , and configured the FidoNet using Binkt .
Every time an event happens, the SBBS Services consumes more than 50% of the
system CPU ( i've even used a last-gen Core i7 as host, and the issue persist
), now the VM is running on its official host a Dual Xeon 5460 based server (
should be more than enough ) , the VM is set for 4 vCPU and 4GB of memory.
I've tried using Windows XT, Windows 2003, Windows 2008 and now Windows 2012R2
all had the same behavior, when it start a Binkt event it uses almost all CPU
available after finishing the exchange process.
Using the Process Explorer i see that the sbbsNTsvcs appears to be in some kind
of loop , on the Microsoft C Runtime
Start Address ucrtbase.DLL!_crt_at_quick_exit+0x20 ( this "loop" is using the
50+ cpu resources according the process explorer ) 
Restarting the comm services solves the problem until the next event get into
place.
Have anyone seen this kind of behavior ? or have any tips where i can
research/fix this issue ?

Regards,

Alexandre F.S.Figueiredo
