I have several 100D's and 90D's in my environment. One unit in particular (100D) is locking up every 2 hours. The errors I get are
FortiGate has reached system file descriptor limit for 1 seconds, the error in the FAZ is Kernel enters conserve mode. The unit rebooted after a firmware update and stated it was not rebooted properly (odd). I am thinking of going up a version to 5.4.2 tonight. I have AV disabled, but not IPS. anyone see this behavior yet?
You need to re-format the boot drive and reload the image of the 5.4.x version then reload the saved config. That's what TAC would instruct when you open a TT. If I member correctly, at least 5.4.0 and 5.4.1 had either or both boot drive and log disk when it's upgraded from 5.2.x. It should have been described in the release notes. That's why we skipped those versions when we upgraded ours. Read the release-notes carefully and follow the instructions.
