It could actually be a physical loss of connectivity, but there have been a series of problems with old/buggy Intel drivers on SecurePlatform. What does the output of "ethtool -i eth0" show? It should be at least v7.6.15.5. I'd highly recommend updating the Intel e1000 driver to the latest version, you'll have to open a case with Check Point support to obtain the latest certified e1000 drivers for SecurePlatform.
