I have a SharePoint Farm with 19 site collections, each with its own application pool. One site collection has some custom code and workflows that were developed by our in house Software team. We have some custom crawls setup that use the BDC to access data from DB's outside the farm. This site collection has over 2000 sites. The site collection has caused issues 3 times over the last 4 weeks in which it begins to consume memory and cpu until the WFE becomes unresponsive.
This happened last night and I've been looking through the logs and I keep seing the same entry repeated
12/29/2009 16:59:51.23 w3wp.exe (0x191C) 0x17B4 Windows SharePoint Services General 8xfr Verbose PermissionMask check failed. asking for 0x00000015, have 0x3C4312EF
The farm used Kerberos authentication and consists of
1 App server hosting the search index and Excel Services
I also see event id errors 27745
Event Type: Error
Event Source: Windows SharePoint Services 3
Event Category: General
Event ID: 27745
Time: 5:44:02 PM
The description for Event ID ( 27745 ) in Source ( Windows SharePoint Services 3 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: #50071: Unable to connect to the database SharePoint_Config on srsql2005prod2. Check the database connection information and make sure that the database server is running..
I've searched the web and I cannot figure out why the entry in the SharePoint log is firing. Does anyone know what is causing this?
