Doesn't seem to be an issue with our logging server as we are taking in logs fine from Windows systems.</P> <P class="_1qeIAgB0cPwnLhDF9XSiJM">We mainly run syslog over TCP and can see the firewalls connecting they just aren't sending any data. Logs internally on the firewalls are being generated with no issues.</P> <P class="_1qeIAgB0cPwnLhDF9XSiJM">Anyone getting the same?</P> Thu, 29 Feb 2024 11:15:54 GMT https://live.paloaltonetworks.com/t5/next-generation-firewall/possible-leap-year-syslog-bug/m-p/578826#M2744 JamesPreston 2024-02-29T11:15:54Z https://live.paloaltonetworks.com/t5/next-generation-firewall/possible-leap-year-syslog-bug/m-p/578830#M2745 <P>Some evidence that this might not be affecting PAN-OS 10.2.8, or might be due to the use of a custom syslog format (mashing into CEF).</P> Thu, 29 Feb 2024 12:06:06 GMT https://live.paloaltonetworks.com/t5/next-generation-firewall/possible-leap-year-syslog-bug/m-p/578830#M2745 JamesPreston 2024-02-29T12:06:06Z
