me too. I've therefore built 64bit binaries which worked much better for
me. Unfortunately I forgot to upload them until now :/ But as of now
they're available :)

This is definitely fixed with the 64bit versions. Microsoft has a weird
concept for the 32bit compatibility mode, which I worked around by
building the 64bit binaries.

Eek, that's not good. Yeah, please let me know that. I'll see if I can
find anything out with that information, but just the file offset is
probably not going to help much :( What version did you use? It says
1.0.0.0 in the file because setting the version for a file it well
hidden and I tend to forget to change that..

Sounds like a counter reset. This could be caused by automatic
restarting of SSC Serv.

Can you maybe create a PCAP file for a host that's having this problem?
Bruno Prémont has recently written a Wireshark dissector for the
collectd protocol, which is wonderful for problems like this one. Good
arguments to tcpdump would be:
  # tcpdump -i $IF -p -s 2000 -w sscserv.pcap udp port 25826 and host $IP
