None of our devices are able to run security and patch manager scans.

 

When running a manualy scan locally with the UI, it times out awaiting connection and we get these errors:

 

 

 

Verifying Device ID with core SERVER    Failed: Core returned error

Updating settings:                                                    Failed: No response from core

Checking for updates on core SERVER  Failed: No response from core

 

 

In the IIS log, there are loads of 503 errors:

When i run http://localhost/wsvulnerabilitycore/vulcore.asmx on the core server, the page i get simply says:

 

 

 

 

 

Server is too busy

I have verified

the permissions to *WSVulnerabilityCore    

LDLogon\VulnerabilityData*   and       LDLogon\vulscanresults

in IIS (basically they are set as per the attached document that another user

posted).

 

We are running 8.8

with the hotfix and patch installed.  The core and db servers are brand

new (introduced 2nd June). They are both 4x quad CPU 16gb machines and the load

on them (12000 nodes) is barely noticeable.  I beleive LDSS has been working since it was setup by ourselves/Pangea but has since stopped working

 

This has completely stumped us - any ideas?
