I'm using get-vieventplus to get events from multiple vCenters on the same report. The report runs for days and never completes. It eats up all the RAM on the VM it is running on - even 12GB of RAM even though nothing else is running on this VM but this report. When I look at the performance chart I can see it go from almost no RAM utilization before the report started, then rapidly up to consume all the RAM on the VM the report runs on, then continues at almost 100% RAM utilization for days. When I log in I see this error on the console of the PowerShell ISE. The error seems to repeat itself multiple times. The error points to line 163 in the get-vieventplus function. I highlighted line 163 that it refers to. Also I included the report below:
#Define and connect to vCenters
$vcenters= "vcenter1","vcenter2","vcenter3","vcenter4"
