    Hi Praveen,

    I just discoverred your great blog today, and will check your photos soon. We are a french based editorial (online magazine) and services (web hosting) website for photography and i do have a problem with my mssql database, left unsolved for weeks, so thought may be i should ask you if you ever faced that kind of issue.

    The number of locks increases all the time although :
    – i can’t see/trigger any ASP error in my code
    – the is NO lock escalation (as trace profile reports)
    – no deadlock chain either
    – the number of locks drop to zero when i restart mssql service but then starts again to grow instantly, reaching thousands after several days
    – enterprise manager logs do not report anything special

    Every single client of us (photographers websites) gets blank pages with a message related to impossibility to connect to the db, or on some pages it’s just one ore more images that won’t display (i use a SP to display images to avoid hotlinking and other similar issues)

    If you have a clue, please let me know, it will be much appreciated !
