User profile sync service stuck on running in CA

Issue:

In Central admin while starting the user profile sync service might stuck on running/stopping. Rebooting that server might not resolve that issue.

Resolution:

Open the Powershell window --> Get-SPServiceInstance --> Once you get the list of GUID, then note the GUID of that service application --> Run Stop-SPServiceInstance --> Start that service through Central admin(services at server).

Unable to restore list libraries from SharePoint 2010 recyclebin

Issue: We recognized a strange issue where SharePoint 2010 recycle bin doesn't allow to restore list and libraries. Different admins were getting different error message in ULS logs.
Resolution: We just increased the list throttling at web app level and it resolved my issue. Hope it would help you as well
