SSRS ReportServer_XXX.log is giving incorrect CPU count I am currently investigating an issue wherein sometimes the SSRS just suddenly stops accepting requests until we do an IISRESET command. This happens after we added an additional processor on the server. No new report is added on that time. Right now we have 2x Quad Core with HT enabled processors. Information in 'sys.dm_os_sys_info' is giving me the correct cpu_count which is 16. However, while looking at the 'ReportServer_XXX.log', I noticed that it's logging incorrect cpu count.

w3wp!resourceutilities!1!3/22/2014-14:29:16:: i INFO: Reporting Services starting SKU: Standard w3wp!resourceutilities!1!3/22/2014-14:29:16:: i INFO: Evaluation copy: 0 days left w3wp!resourceutilities!1!3/22/2014-14:29:16:: i INFO: CPU throttling turned on w3wp!resourceutilities!1!3/22/2014-14:29:16:: i INFO: Running on 127 physical processors, 255 logical processors

I am not certain if this is the cause but either way, how do I correct this issue? The count is way off.

Also, on our other server, the CPU throttling turned on message is not being logged. Could also be this another reason?

SSRS is running under this environment:


Windows Server 2003 R2 32-bit (PAE enabled)
SQL Server 2005 SP4 (AWE enabled) 
2xQuad core with HT processors 
64GB memory
I think the "CPU Throttling" message indicates that the server has a power setting enabled that will dynamically reduce CPU speed to conserve power (usually the "Balanced" power scheme set in BIOS). Not sure if this is related to your issue, but you probably don't want it enabled on a server.
