How to restart httpsd on Fortigate 110C

Hi,

I have a Fortigate 110C that I have Web able to connect to via the web interface up until today.

I started to get HTTP Error: 400 messages after entering in my login details.

No pages would display.

I can login via an SSH session to the CLI.

I checked the KB and found articles that describe the problem and the answers were to use get system performance top

and find the pid numbers for the httpsd services/processes. Then to use diag sys kill 11 <process-Id> to restart the relevant processes. However this has not worked. The pids are now listed by fnsysctl ps as having a status of Z (zombie).

Now I cannot get a login page to display.

I have tried resetting the admin-sport value to a different port number however this has not worked. The httpsd processes are still in a Zombie state and I cannot get a web login page to display.

How can I get the httpsd processes to restart fully without having to re-boot the Fortigate unit?
