I would like to disucss an issue that we have since the installation of Windows Updates last weekend.
At one of our customers we installed the Windows Updates last weekend. This was the first time in 1,5 years.
After we installed the updates we had issues on all servers within the SharePoint farm (SP2013):
- SPHA not opening
- Timeouts on webapps (ASCX controls not loading)
The timeouts we received on all webapps and on different pages.
After many troubleshooting we still didnt fix the issue. We tried:
- Re-provision webapps (re-enable SharePoint Foundation web application service_
- Config cache cleanup
- Cleanup ASP.NET Temporary Files
- Update .net to 4.5.2
- Restart Cache Cluster (distributed cache)
- Reinitialize-SPResourceSecurity
We were able to fix one server. But the other front end server is still not working.
I think its related to the ASP.NET Temporary Files. On the server which does work the directory was created within couple of minutes. On the malfunctioning server the temp directory is not filled within 1,5 hours. Every ASCX compilation takes about 1 minute.
As SP needs alot of ASCX files it receives a timeout. After refreshing the page we get after a couple of minutes again a timeout with another reference to a different ASCX file. We compared every web.config on the server to check if debug is set to false.
But also that is not the case.
Please help :(
