CPF incompatibility with netlimiter

I’ve noticed that CPF 2.3.5.62 crashes netlimiter 1.30 after 15-20 minutes. I’m not sure if this is an issue with this build as I’m a new user, but I can say with certainty that this did not occur under NIS, Sygate or Kerio. I need that app due to my shared and quirky DSL connection. Just wondered if anyone else has come across this behavior or has a workaround.
ps.
I’ve been watching the progress of this firewall and just wanted to say thanks for the hard work!

I have just installed CPF on one of my PC’s. I run NetLimiter 2. There does appear to be some sort of issue, but it may be solvable by a CPF setting or rule. I do not get a crash, simply an error on NetLimiter saying it cannot connect as the RPC server is unavailable
