SharePoint Logs – Tracing service lost trace events

Some time, my SharePoint logging didn’t work properly for some reason, if I looked into my SharePoint Logs directory then in every generated log file, I have found below lines.

Date and time        wsstracing.exe        (0x07E4) 0x1634         ULS Logging  Unified Logging Service uls1        Monitorable              Tracing Service lost trace events.           Current value 8.

Solution:

I need to restart my logging service, SharePoint uses "Windows SharePoint Services Tracing" service for writing logs into ULS logs, so I went to services and restarted my "Windows SharePoint Services Tracing" services, once I did that, a new logs was created into SharePoint logs file. I also found out that might be this errors showed due to upgrade of service pack 1.
