you have to tune the reporting queries eventually.
this is not a simple process, as you need to check the queries of the one that "block" the others as they run long time, and use (block) resources long time.

if you have a reporting on the OLTP database, you might consider to replicate the users database to a reporting database, so you separate the OLTP transactions completely from the reporting queries.

depending on what reporting you have, it could be a daily full backup + restore, or indeed a full transactional replication.

Thank you for filing this issue. The RS database architecture can lead to blocking under heavly load. Best practices for how to address this issue are documented here: http://sqlcat.com/search/searchresults.aspx?q=reporting+services&ctypes=blog

We will consider this issue for a future version of Reporting Services.>

EugeneZ, The problem that is described in the provided article by you  is exactly the problem that we are having: SSRS 2008 - giving blocking error on Writelocksession Stored procedure in Report server database.
Blocking in SSRS ReportServer Database
http://connect.microsoft.com/SQLServer/feedback/details/698388/blocking-in-ssrs-reportserver-database
Additionally to add is that SSRS is not heavily loaded.
Second link forwards to url which returns 66 blog posts, and not anything specific.
Do you have any specific link for this issue?
@angelIII, It is OLAP database, @SThaya, I am not accessing remote server, the problem is with locking in the reporting database as listed in the link.
