csrss.exe used up 176,399 Handles
Hi,one of windows server 2003 R2 Enterprise Edition with service pack 2 running email application is having csrss.exe used up 176,399 Handles. i used sysinternals process explorer found it is sub-process under smss.exe. i also found some articles from internet saying that any process used handles more than thousand will cause system problem. Just wonder will scrss.exe cause system performance issue? and how to troubleshoot on this problem.Thanks

Hi, Generally speaking, if there is a handle leak in csrss.exe, your system should be unresponsive or other symptom that you would notice. If there is no noticeable problem, we can monitor it currently. If the system cannot work properly, you may try the hotfix below: 957216 A handle leak occurs in the Csrss.exe process after the desktop heap is exhausted on a Windows Server 2003-based computer http://support.microsoft.com/default.aspx?scid=kb;EN-US;957216 For more information about handles, please refer to the following article.
