Scanner behavior after upgrade to 11.1.3

[jduke_halls]

Since upgrading to Lansweeper from 10.6.0.0 to 11.1.1.3. we have had a TON of performance issues. CPU on the scanner was normally around 10-15% during our scanning window. Now, at idle, it's at 35-80% CPU utilization.

We have disabled AD Scanning, yet LanSweeper still requests Kerberos tickets at a rate of 130-150 per second (yes, over 30000 tickets in a 5-minute period from the LanSweeper server). We have performance- tuned the scanner, turned off ALL WMI queries, and are now at a loss for what this thing is actually doing.

The scanner in the new version is acting like Malware, and, since we just renewed for a year, I'd rather not bin it, but I'm getting very tempted to do so.

Already opened a ticket. The support team has been an absolute joke. Doesn't respond for over 24 hours at a time.

The issue isn't the scanning queue. The scanning queue literally has nothing in it. The issue is the LanSweeper service, whenever it is on, launches a DoS attack on our Active Directory servers, despite nothing in the queue and all Active Directory scans turned off/deleted.

We're leaving the service off until this gets fixed. If it doesn't, we'll likely look to refund/cancel our year that was just re-upped 2 weeks ago.

Oh sorry. I replied to the wrong post.

I'm having the same issue, I noticed it today. Scanning queue is full of computers and I see no progress.
The service process seems to have some kind of memory leak. I stopped it when it got to more than 5gb.

Same problem here. Assets get stuck in the queue and only manually clearing the queue helps.

I opened a support case at lansweeper and so you all should do.

I wish it was just the queue going up and not clearing. This is with absolutely nothing in the scanning queue, nothing select to scan, just starting the service up.

Support did get back to me and have me run a query, since there was a known issue about a FK relation not working, but that didn't solve our issue at all.

So if you check your error log under Program Files (x86)\Lansweeper\Service\errorlog.txt and see: 

"The DELETE statement conflicted with the REFERENCE constraint "FK_tblLinuxSoftware_tblSoftwareUni"

in it with a stacktrace, run this SQL using SQL Management Studio, or the Query Tab of the DatabaseMantenance.exe under the tools directory:

USE lansweeperdb
DELETE FROM tblServicesUni WHERE ServiceuniqueID IN (
SELECT ServiceuniqueIDFROM tblServicesUni
WHERE ServiceuniqueID NOT IN (select ServiceuniqueID
FROM tblServicesGROUP BY ServiceuniqueID)
)

We have noticed the exact same issue since updating to 11.1.3

CPU usage is now at or close to 100%

It's not good!
