Deadlock Error



I am new to EPIServer. I am getting this error on my production server


Type : EPiServer.Core.EPiServerException, EPiServer, Version=5.2.375.236, Culture=neutral, PublicKeyToken=8fe83dea738b45b7

Message : Deadlock risk detected. Trying to read a page from the same thread that is already trying to read the same page.

I dont know much about the flow of the code. Need some help/advice on what could be the cause of this error and also how to resolve this issue.

Thanks in advance
