Description	A request to create a new worker process has arrived. The '%1' setting has been reached. The Windows Process Activation Service (WAS) will not start any worker processes until this drops.
Event Information	According to Microsoft : Cause : This event is logged when request to create a new worker process has arrived. Resolution : Configure the dynamic idle threshold If Web server performance is impacted, you may want to configure the dynamicIdleThreshold attribute of the system.applicationHost/webLimits section in the ApplicationHost.config file. Note : For more information about the values to use for the dynamicIdleThreshold attribute, see IIS 7.0: webLimits Element (IIS Settings Schema). To perform this procedure, you must have membership in Administrators , or you must have been delegated the appropriate authority. To specify a value for the dynamicIdleThreshold attribute: Open an elevated Command Prompt window. Click Start , point to All Programs , click Accessories , right-click Command Prompt , and then click Run as administrator . Type cd %Windir%\system32\inetsrv\ . Type appcmd set config /section:webLimits /dynamicIdleThreshold :number where number is a value from 0 to 10000. To verify that the value has changed, type appcmd list config /section:webLimits /config:* The changed value will be displayed. Verify : Because the dynamic idle feature works in real time, its threshold value is transient. However, you can verify whether dynamic idling has been enabled, or specify a value for the dynamic idle threshold if you want. To perform this procedure, you must have membership in Administrators , or you must have been delegated the appropriate authority. To verify whether dynamic idling is enabled: Open an elevated Command Prompt window. Click Start , point to All Programs , click Accessories , right-click Command Prompt , and then click Run as administrator . Type cd %Windir%\system32\inetsrv\ . Type appcmd list config /section:webLimits /config:* The output will resemble the following: webLimits maxGlobalBandwidth="4294967295" connectionTimeout="00:02:00" demandStartThreshold="2147483647" dynamicIdleThreshold="0" headerWaitTimeout="00:00:00" minBytesPerSecond="240" /&gr; If the value of dynamicIdleThreshold attribute is non-zero, the feature is enabled. In the example here, it is disabled; this is the default setting.
