Hi all,
I've been working on this one for a while, and I really hope someone can help.
The problem description and notes are below:
Problem Description:
Users across WAN connections are being disconnected from their Citrix sessions
with varying frequency. Users are reporting that they are usually performing a
file operation like opening an Office file or saving a document. Some users
are being disconnected when they start up an application that is tied to a
backend DB. All the DB servers and file servers are located in the data center
with the Citrix servers.
Notes:
- For some users, this happens once a week, while others report 2-4 disconnects
per day. Most users report somewhere between those two.
- Farm is MetaFrame XP FR2 with SP3. Clients are either 6.30 or 7.1.
- Does not seem to be server specific, although clients have identified servers
that they feel are better than others.
- Disconnections don't seem to be application specific, except for the
DB-related disconnects, which can only be one application.
- Users receive the "trying to reconnect" message from the Citrix client only
part of the time. Other times (an almost equal amount) the users receive no
message at all - the application just disappears. In either case, the PN icon
in the system tray flashes as if it's lost its connection.
- Sometimes on reconnection, the users will receive a message saying that they
already have too many instances of the applications running. This usually
happens when they receive no "trying to reconnect" message. The server shows
the session state as "active."
- Users in the same location as the servers do not have any problems.
Thanks in advance,
Gabe Knuth
