Hello Jacob,
2 Things i found out about "Retransmitted data does not match original data".
First is a problem with http keep-alives mostly from proxy servers, checkpoint does not support this kind of keep-alives (SolutionID sk15619).
Second was my problem, i had a router which calculated the TCP Checksum incorrect for some packets. A TCP session flows correctly, then a packet gets a bad checksum, the web server does not respond to the packet (normal). the client retransmits the packet, this one has a correct checksum arrives at the firewall and the Checkpoint Rejects the packet with the "Retransmitted data does not match original data" message.
I suggest you use de "fw monitor" to determine which is your problem.
Regards, Ronny

I've just recently started getting these errors on my firewall: "Retransmitted data does not match original data". There have been no changes lately. I even upgraded to the latest IPSO version and hotfix level but still no difference. The cpu also stays around 68% and often spikes up to 98%. Any info is appreciated.
Thanks,
