Posted a similar question recently, and thought I had found the solution, but now recently encountered it again, so I'm going to repost with the new information ...
I'm afraid I'm at wits end here, so hopefully someone can at least point me towards the right idea.
I'm currently running Reporting Services 2005, SP4, using IIS 6.0, on a Windows Server 2003 SP2 machine.
The issue that I'm facing is that, very regularly, the website where the reports are delivered (localhost/reports and the equivalent using the machine name for non-internal access) becomes completely unresponsive. The page is stuck loading, and never completes.I
I found a pseudo-solution to the problem recently. If I recycle the application pool associated to the reporting services IIS page, the website responds again - but only for a short time, after which it becomes unresponsive again. Restarting IIS also resolves the problem, but again, only for a short time.
I've checked the windows application logs, the IIS logs associated to the reporting services webpage, and the reporting services logs - none of them provide me with any additional information as to why this is happening.
Has anyone experienced this before? I have absolutely no idea where to look next.
