Although we have dealt with this on Win2k3, we ended up backing out of it due to problems. We had an app that was using a ton of memory and was limiting the amount of users we could get on a server. We took them to the enterprise Edition and went to 8GB and enabled PAE. We had issues with the servers crashing upon logon that we *think* we could track back to Kixtart, or at least the version we were running. The servers were not yet in an AD and were still part of an NT4 domain. We needed to upgrade to a newer version of Kixtart and we had issues when we did that. We worked with Microsoft for a few weeks on this and they came back with the recommendation that we were focusing too much on the PAE issue and we should be focusing more on the app itself since it was internally written. In our case we were able to have a developers work with MS and optimize the memory usage. That would be an option. Another would be additional hardware. Another would be the apps like Tscale that are supposed to help with memory utilization. Either way, we ended up backing out of the PAE switch after working with Microsoft. Apps have to understand how to use the additional memory so we just use it now for things like Exchange and SQL. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] Sent: Wednesday, May 18, 2005 7:25 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: How much Memory in servers On 18/05/05, Dogers <dogers@xxxxxxxxx> wrote: > On 18/05/05, BRUTON, Malcolm, FM <Malcolm.BRUTON@xxxxxxxx> wrote: > > > We have an application that sporadically does "out of memory" errors > > > It is an in-house developed app and the guys that develop it say > > that we should add more memory to our servers.

Without that, you can't use more than 4Gb RAM Andrew ******************************************************** This Weeks Sponsor: ThinPrint GmbH Now available: The new version .print Engine 6.2 with SSL encryption and certificate management. http://www.thinprint.com ********************************************************** Useful Thin Client Computing Links are available at: http://thin.net/links.cfm ThinWiki community - Excellent SBC Search Capabilities! http://www.thinwiki.com *********************************************************** For Archives, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link: http://thin.net/citrixlist.cfm Email Confidentiality Notice: The information contained in this transmission is confidential, proprietary or privileged and may be subject to protection under the law, including the Health Insurance Portability and Accountability Act (HIPAA).
