pf: BAD state: TCP...

[David Beck]

Hello,

I have problem with pf and didn't find any information that would help. 
Could you please advise on this? I wanted a simple thing, create a jail, 
and put a squid server into that. It didn't work as expected. Later I 
phased out squid and just wanted to open a TCP connection from the jail 
to the outside world. The interesting thing is that, 4 out of 10 
outgoing connection goes as expected and the rest blocks. Then I started 
to play with pf. My last attempt was that I increased the debug level, 
then I got these messages:

I found the place in the source where these are generated, but that 
didn't help me. Any ideas?

Thanks in advance,
