This message comes from linux/net/sched/sch_generic.c. It seems to be a warning about some sort of a locking problem in the driver/networking code.

At least in kernel 2.6.18 there was a kernel locking mistake that caused similar symptoms.

Ensure you're up to date with kernel patches.

What's the name of the Linux distribution you're running?

I think it would be best to take this up with CheckPoint's support people then.

It would seem that when this message is displayed, a packet might get dropped. I don't know enough about Linux kernel internals to be sure about that.
