Listener Channel Failures, Process Activation errors, Licence Acquisition failure. It’s all happening today…

Just had an interesting error crop up at a client site. One of the team (Hi Daniel!) was building a SharePoint server and was halfway through configuring it, when it suddenly stopped working. 503 errors on all web sites on the server, and some very strange errors in the event log:

Event ID: 8200

Source: Security-Licensing-SLC
Log: Application
Level: Error
Details: License acquisition failure details. hr=0x8004FE33

Event ID: 5139
Source: WAS
Log: System

Level: Warning


A listener channel for protocol ‘http’ in worker process # serving application pool ‘SharePoint Central Administration v3’ reported a listener channel failure. The data field contains the error number.

Event ID: 5002
Source: WAS
Log: System

Level: Error


Application pool ‘SharePoint Central Administration v3’ is being automatically disabled due to a series of failures in the process(es) serving that application pool.

WAS is the Windows Process Activation Service (you’ll need to know that shortly). I’m not sure what the root cause of this error is, but someone somewhere in Microsoft does. Essentially, if you are using IPv6 and have nominated a Dedicated Crawl Server, the SharePoint application writes some bogus entries to the Windows Host file, causing WAS to fail.
The solution is to either:
  • Set up the SharePoint crawl service so it uses all WFE servers to crawl content (as Central Admin is FUBAR’d, you’d need to use STSADM to change this property), or
  • Remove IPv6 from the Server NIC’s and restart the Windows process Activation service.

This then writes nice entries to the Hosts file and the problems evapourate like morning dew on a hot day. This is the site that we found the solution on – (we used Workaround 2).

    Hey Brad, Can you please post exact STSADM command to change crawl service to use WFE. I am having same issue. Central admin is not working. Thanks

    Actually, I\’ve just had a quick look – and I cannot find one. The solution might be to fix the problem using option 2, then set it up with option 1, then switch back to IPv6…
