[FW-1] Firewall refusing any new connections



Lately I have been experiencing a weird problem with FW1 4.1 SP2. Its seems
that at random intervals it refuses to accept any new connections. When you
try to telnet to something behind the firewall you see the Checkpoint banner
come up and then immediately drops the connection. Logging completely stops,
but all existing established connections are unaffected. The processes show
all of the necessary FW1 daemons are running. Below are the fw ctl pstat
results:

Now the weird thing is that everything returns to normal when I push a
policy, even if I have not made any changes.
Any feedback or advise on this issue would be appreciated.

Thanks.
