    Hi Experts,

    I have a windows service running every minute and has many database operations to perform. It runs perfectly for many days, sometimes it suddenly stops and throws this exception. Later when we start to debug it, the exceptions goes off, but if we don't debug, the exception continues to come. We are tired of this totally random scenario. Please assist us with this.

    We are using sqlhelper.cs for database interaction.

    It seems a DB problem, but i connected through Sql Management studio and iam able to do everything through it (Like querying,updating etc...), just through code is the problem.

    The service is calling DB very frequently. Since three hours the service is responding well and no sign of DB overloads. Also it had been on for 20 days without rest and everything was well.

    I will post the message if i get this exception again, i already cleared my logs before.

    The additional insight into the problem is every method going to DB suffers the same exception. Like simple update statement running within a second now takes more than 30 seconds when this problem comes up.

    So i got curious as whats the main issue.

    Hope this helps to get hold of problem.
