After update firmware to 7.0.4 I try to see GUI dashboard widget "Firewall Users" and device down with error "Failed ti retrieve info". In ssh console after same minutes
# diagnose sys top[sys_top:559] fork() failed: (12)Cannot allocate memory
and not answer.
In com-port connect console:
fork() failedfork() failedfork() failedfork() failedfork() failed
https debug not show nothing, it stoped after open page with widget "Firewall Users"
Can you please try to reboot the FGT and check again?
> C195FW001 # diag sys top[sys_top:560] fork() failed: (12)Cannot allocate memory
Regarding this error message, please run the command #diag sys top-summary & whichever, process is consuming high memory then kill it as the following.#diag sys kill 99 <process_id>How to interpret the process_id, please review the below kb article on it.https://community.fortinet.com/t5/FortiGate/Technical-Tip-Diagnose-sys-top-CLI-command/ta-p/190238?e...
If your fortigate is a low-end series model, it may not have enough memory to run the firmware.
Check also the "diag sys flash list" - you should see at least 10% available space for the active partition (the one with "Yes")
