Read timed out error while searchTasks opertaion

Dear All,

We are getting a read timed out error while using searchtasks service of task client. This is not a regular issue and if we resubmit the step, it usually works.
This error has started appearing off late so it is definitely due to db size being increasing.

Is there any way to get around this error?

Thanks in advance,
Ninad Patil
