508 Resource Limit Reached when trying to disable Pingbacks

Hi,

Just setup a new multisite and hosted with fastcomet.

When I go to Defender >> Hardening it lists some problems I need to fix which all work with the exception of Disable Pingbacks.

When I click the fix for this it maxs out my entire account, 2Gb of ram, 100% CPU and all 20 entry processes and I get a 508 Resource Usage Limit reached error.

Have never had this happen with a plugin before and should not happen for something as straight forward as turning off pingbacks which I can do manually anyway but was just giving Defender a test drive.

Thanks,
Rob
