If you are in an environment with a separate management server/log server, then the cause could likely be that the firewall is unable to send the logs to the management server, and the buffer allocated for the logging has been filled. Thus, as new log entries keep rolling in, the older ones are lost as it is indicating. I have experienced this before. The cause for being unable to send the logs could be disk space or could also be communications with the log server.

If it's local logging, then the filesystem being full would make the most sense, as the first responder explained.

This cause that the firewall is no passing packets.

Somebody have any idea how can I fix this problem?

This firewall has Linux RH 3 and checkpoint NGX R60
