High CPU Utilization on Inventory Central Server 16 Release 6
Anyone else experiencing high CPU utilization on most recent inventory release? My CPU is pegged at 100 on my central server. Looking at Windows event logs, I keep seeing a repeat of a warning, 60020. Same thread listed in each one. Wondering if I have a stuck scan or job of some sort.

Having the exact same issue since the 16.6 upgrade.
I have a case open, no engagement on it since yesterday. Just pinged sales to see what is going on. Will update thread with resolution if one is found.
Glad to know I have company at least.
Same here.
@Jason & @Curtis_Hendzell Did you guys open cases as well? Where are you in your case if so?
No I have not, but I can if you think it will speed things along. So slow even just scanning.
I have a support ticket in now.
Support had me send DB over to them, they report it is being forwarded to development.
Same here
They asked if I had rebooted the server PDQ was installed on. I had already rebooted once but did it again and seems to have helped. CPU usage has been between 0% and up to 30% when scanning a large number.
Any other changes?
They had me turn off "heartbeat" and then do a scan but it didn't change anything
They had me install an update (16.6.0.2). Seems ok so far.
Just received the same update myself. Definitely helps the situation, but still very CPU intensive.
My CPU usage stays around 0%-5% only jumps momentarily when doing a large scan, so mine seems good to go.
They send me 16.6.0.8, but still 99-100% CPU utilization. They asked for the DB and it has been forwarded to development.
I am running same as you, but no CPU issues. Support did review my DB and provided guidance on performance improvements:
Last, if you have any collections using the "member of collection" filter, let's change that to its more reliable filter-cousin "computer collection is member" instead. Development has been able to find a performance issue that is directly related to using that particular filter.
Not totally sure why this is not a little more publicized, but sounds like a good way to improve performance. I have a ton of these in my environment that I am starting to remediate.
From Ticket #154507
One of our clever guys here wrote a SQL report to find filters which might need changing:
Select Collections.Name as "Collection", reportdefinitionfilters.Value as "Filtering for this Collection" from Collections join reportdefinitionfilters on Collections.ReportDefinitionId = reportdefinitionfilters.ReportDefinitionId where reportdefinitionfilters.tablename = 'Collection'
