SharePoint site cannot access until we recycle the application pool in IIS

Question

Hi,

We have a SharePoint site cannot access frequency. It can access when we recycle the site application pool in IIS. However, the site cannot access again every few hour.

Any idea to check or fix the issue?

Thanks

Hi @Chong ,

Welcome to Q&A forum!

Based on the information we have so far, we cannot determine the cause of this issue. But don't worry, let's try the following methods to troubleshoot:

1. Issue Scope: Check if this happened to all sites and users.
2. Check Event Logs: Look at the Event Viewer on your SharePoint server for any errors or warnings that occur around the time the site becomes inaccessible. This can provide clues about what might be causing the issue.
3. Review ULS Logs: SharePoint's Unified Logging Service (ULS) logs can provide detailed information about what's happening within SharePoint. Look for any errors or unusual activity that coincides with the access issues.
4. Monitor Resource Usage: High resource usage (CPU, memory, disk I/O) on the server can cause performance issues. Use tools like Performance Monitor to check if there are any spikes in resource usage when the site becomes inaccessible.
5. Check Application Pool Settings: Ensure that the application pool settings in IIS are configured correctly. For example, make sure the application pool is set to recycle at appropriate intervals and that it has sufficient resources allocated.
6. Review Custom Code and Solutions: If you have any custom code or third-party solutions deployed on your SharePoint site, review them to ensure they are not causing the issue. Sometimes, poorly optimized code can lead to performance problems.
7. Update and Patch: Ensure that your SharePoint and IIS installations are up to date with the latest patches and updates. Sometimes, known issues are resolved in newer updates.

Hope these can help. :-)
