I got a SharePoint environment consist of Web Servers, Index Server and Database Server. The SharePoint application has been down for unknown reason, after I check on the event viewer and the result as below:
Event ID : 1013 Computer : Web Server Description : A process serving application pool 'AppPoolName' exceeded time limits during shut down. The process id was '4820'.
Event ID : 8645 Computer : Database Server Description: A time out occurred while waiting for memory resources to execute the query. Rerun the query
Additional 2 informations found in Web Server:
Event ID : 1117 Description : A worker process with process id of '4820' serving application pool 'AppPoolName' has requested a recycle because it reached its private bytes memory limit.
Event ID : 1077 Description : A worker process with process id of '7352' serving application pool 'AppPoolName' has requested a recycle because it reached its virtual memory limit.
I need help to understand more about the error and how can this happen, example how can the application pool being shut down. Please advice.
Thank you in advanced.
Addition: I would like to know what is the tool normally use to keep track of memory leak by SharePoint.
