IIS Performance Issues

We are having performance issues with SafeGuard 5.5 client’’’’s sync'ing with the management servers whereby it takes an extraordinarily long time for them to properly register and receive the appropriate certificates and keys.

From looking at the management servers this issue would appear to be with the performance of the IIS servers; the w3wp.exe process consumes 100% of CPU time (of a single core) and the processes keep being recycled due to the following:

Event Type: Information

Event Source: W3SVC

Event Category: None

Event ID: 1077

Date: 14/09/2012

Time: 10:17:07

User: N/A

Computer: <server>

Description:

A worker process with process id of '5092' serving application pool 'SGNSRV-Pool' has requested a recycle because it reached its virtual memory limit.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Has anyone experienced this issue and can offer some help to resolve the problem?

Cheers,

James
