7.6.0 WAD memory leak, Fortigate 200F

[bevvet]

So been running 7.6.0 since it has come out on my home fortigate. In 56 days the memory usage rose to about 83-84% when I just happened to log in and notice the high usage. 8 WAD services using about 13.3% usage each. Restarted WAD and memory dropped back down. Wanted to let the community know what I came across, don't have support on the fortigate so not able to open a ticket with them to provide them any information to help them discover the cause.

Thank you for sharing your findings. Are you using any policy in proxy mode?

There is a known issue (1042055) related to it, the issue is already fixed and will be included in 7.6.1.

Hello  @bevvet ,

Thank you for contacting the Fortinet Forum portal.

-As mentioned by my colleague there is known issue but for time being if you would like to kill the wad process to optimize the memory configure the below automation stitch which helps to restart the wad process.
