[vivekdomadiya]

hello,

I'm using FortiGate 100F with FortiAP, and last few days I observed Randomly All APs are disconnecting from FortiGate and connecting automatically after some time

So i checked Crashed logs diagnose debug crashlog read

and please find output below,

Can anyone help me to solve this and what would be the reason behind killed cw_acd process.

Hello,

In order to verify whether process was killed by the system or administrator. You can search for string below:

Signal <> was sent to process <> by user <>

In case you cannot find such string, then it is likely that process was killed by the system. And I would like to ask which firmware you are currently running?

they are running firmware version 6.4.4 and I suggest they upgrade the firmware to 7.0.9.
