Hi, everyone. I'm relative newbie to the list and don't respond much but this is one issue I can relate to. Has anyone seen this where winlogon.exe eats up CPU? We first started having this problem a few months ago and got around it by upgrading NFuse from 1.51 to 1.71 and load balancing XML requests across 6 servers. Last week the problem all of a sudden popped up again. While the problem was happening I found winlogon.exe was spiking the CPU on one of my Citrix servers. I added 3 more Citrix servers to NFuse load balancing, so now were in good shape. Could the cause of the problem have to do with communication between the Citrix server and the data store, rather than the Citrix server itself? Environment: 6 NT4 TSE and 3 Win2k TS in New York plus another 20 NT4 TSE globally. NFuse 1.71 running on Windows 2000 / IIS 5. Thanks, Ruben Mason Dively <mdively@xxxxxxxxxx> wrote:Ron-- I'm not sure--we haven't had this happen since last Tuesday and Wednesday. I will monitor this process should this occur again in the future (god-willing it won't.) Our problem might have been related to things that Rose and Andrew mentioned. This started occurring at the same time that the internally developed software that our application servers contain was upgraded. After the software was upgraded we began to see our application servers getting killed by runaway processes and had as many as 5 to 7 application servers lock up each day. Once the code was corrected for the software that our application servers were providing, the NFuse problem mysteriously went away. It makes sense to an extent that things would start acting hokey when a handful of machines are unable to respond, but the whole thing with the web client popup window not going away threw me off. It did this on both of our web servers--it was just kinda odd. Thanks, Mason B.

One of them maybe hung and = =3D3D will not accept connections. I have had a similar issue but not with Nfuse. At roughly the same time =3D3D each day the farm would stop accepting connections. What it ended up being = =3D =3D3D was a corrupt server with 18 connections on it. The server would not allow = =3D3D anyone to log onto it but was only a problem when all the other servers =3D3D reached 18 users and load balancing tried to connect new users to that server. We have 100 MF servers so it was hard to detect. I found it by doing a Qserver in the morning to see if any stats on a server stood out. This does not explain why a reboot of the DC temporary resolves the = =3D3D issue though?

We started with = =3D =3D3D Nfuse 1.51 when we originally built our farm, and used the Custom Web Site = =3D3D builder that shipped with Nfuse 1.51 to build multiple sites on our Nfuse =3D3D servers. These websites that we created with the website builder have worked perfectly fine since they were first created over a year ago. Just = =3D3D within the past two days, each day around 2:30 in the afternoon (peak logon = =3D3D time for our farm?after lunch rush), we have experienced the following =3D3D problem. We suddenly see the number of current web connections jump dramatically =3D3D up on both of our web servers (this might be something network =3D3D related?haven?t pinpointed the cause here) and then both of the websites stop =3D3D responding. What I mean by stop responding is that when a user points their web = =3D3D browser to the login page, the initial login page will load but then the window =3D3D that pops up to che ck whether the ICA client is installed on the local machine just sits = =3D =3D3D there and hangs. The ICA client popup window never closes as it normally = =3D3D does when the website is working properly. If you try to close the ICA =3D3D client popup window and then login to the website?it just basically sits there =3D3D and spins?doesn?t ever bring up an application set. The first thing we = =3D3D tried is restarting IIS, but this did not change the outcome. After this we = =3D3D tried rebooting our webservers (one at a time) and then trying to load the = =3D3D initial login page?even with a very small amount of web connections to the web servers the page still does not function properly. Our next step was = =3D =3D3D to bounce our primary data collector?the box that both of our webservers = =3D =3D3D are pointed to for their published application information. Once the =3D3D primary data collector is rebooted and comes back up, the problem seems to go = =3D =3D3D away. This is where we are stuck. Why does rebooting the data collector fix = =3D =3D3D the web servers abilit y to display the Nfuse websites? It is very odd that the web ICA =3D3D client window would just stick there and not allow us to login to the page, = =3D3D but as soon as we reboot the data collector the site starts functioning =3D3D correctly. This puppy is nasty and we obviously don?t want to deal with rebooting = =3D =3D3D our data collector every day in the middle of peak login time. =3D3D20 Does anyone have any ideas as to what might be causing this problem? = =3D =3D3D Any help is greatly appreciated?I?m buying beers for anyone who has the fix =3D3D for this one!!! =3D3D20 By the way?don?t ever let your farm dump on you during IForum?there are =3D3D no Citrix SE?s available right now!! =3D3D20 Thanks, =3D3D20 Mason B.
