Some times SharePoint logs show some weird junk lines like:
"wsstracing.exe (0x0984) 0x1728 ULS Logging Unified Logging Service uls1 Monitorable Tracing Service lost trace events.Current value 230. "
1. Restart the WSS Tracing service.
start-> programs -> administrative tools -> services -> Windows Sharepoint services Tracing service.
2. Restart the Windows Administration service Adminsitrtion service also.
