Troubleshooting Configuration Manager IIS WSUSPool Crashing During Sync Error. I’ve also getting this error in the past week: IIS WSUSPool Crashing during Sync Configuration Manager Software Update Point, also WSUSpool stopped due to not enough private memory limit, changed it to a higher limit (4194304).
When the Configuration Manager IIS WSUSPool crashes during sync, there are a few steps you can take to troubleshoot and resolve the issue:
- Check the event logs: Check the Application and System event logs on the Configuration Manager server for any errors or warnings related to IIS or WSUSPool crashes. This will give you a starting point for troubleshooting the issue.
- Check the WSUS server: Verify that the WSUS server is functioning correctly and is not experiencing any issues. Make sure that the WSUS server has enough resources to handle the synchronization process.
- Check the IIS settings: Verify that the IIS settings on the Configuration Manager server are configured correctly. Check the application pool settings, such as the identity, memory limits, and recycling settings.
- Restart the WSUSPool: If the WSUSPool has crashed, you can try restarting it to see if that resolves the issue. To do this, open IIS Manager, select the WSUSPool application pool, and click the “Recycle” button.
- Increase the memory limits: If the WSUSPool is running out of memory, you can try increasing the memory limits for the application pool. To do this, open IIS Manager, select the WSUSPool application pool, and click the “Advanced Settings” link. From there, you can adjust the memory limits.
- Install updates: Make sure that all SCCM, WSUS, and IIS updates are installed on the server. Updating these components can often resolve issues related to crashes.
- Check for third-party software conflicts: Make sure that there are no third-party software conflicts that could be causing the issue. Disable any antivirus or firewall software temporarily and see if the issue persists.
By following these steps, you should be able to identify and resolve the issue with SCCM IIS WSUSPool crashing during sync.
Increase IIS Private Memory Limit
1. Start the IIS console on a server that hosts the WSUS pool. Navigate to your pools;
2. Select WSUSPool and click Advanced Settings;
3. List down properties. Select Private Memory Limit (KB) and enter the new size (in KB), click OK;
4. Click Recycle to restart the pool;
NOTE: If the problem still exists, try to increase the memory size to the pool, also you can set 0 – unlimited memory, but it’s not recommended.
