Insufficient resources - network connections die

[Frank Dreyfus]

Hi,

I am getting fairly frequent insufficient resources errors. These seem to
be mostly related to network connections.

Sometimes, a mapped drive will just stop connecting after a while.
Sometimes I will be unable to make a network connection. Browsing will
fail as will e-mail connections and probably all other network connections.

Some e-mail clients will report insufficient buffer space. Other
applications will report insufficient resources.

Sometimes, some app or other will report that it can't access the
clipboard. This isn't a network error but seems to happen at about the
same time as the network problems.

The trouble starts after some hours of fairly heavy activity with multiple
applications running.

I tend to use multiple network connections to local and remote servers;
keep several web pages open at once; and when I check for mail I check 8
different accounts all at once. However, I would expect the e-mail client
to release connections as soon as it finishes checking for mail and I don't
think browsers keep connections to web servers open.

I have a hunch that some application or Windows XP Pro itself is not
releasing some resource promptly. But what?

Is there a tool that will tell me what applications are keeping network
connections open?

Is there a fix for this?

Is there a limit to the number of network connections that can be open?

Thanks, Frank

Perhaps the task manager will show that a process is using up a lot of
memory?

Perhaps the task manager will show that a process is using up a lot of
memory?

The task manager only shows what processes are open; not how many, if
any, network connections each process is using.

This problem continues. I would really appreciate some help.

Since it's been over a month with no help, I'm including the original
problem description below...

I'm far from a WinXP expert, but you may be looking for the wrong thing.
In other words, the issue may not be the number of network connections
that are open, but -- as the error message says -- an insufficient
amount of system resources. One cause of this is a "memory leak" or, as
you said, "some application ... is not releasing some resource."
http://support.microsoft.com/default.aspx?scid=kb;EN-US;130926 "Using
Performance Monitor to Identify a Pool Leak" may be of some help with
tracking this down. If you haven't used Performance Monitor (I haven't,
myself) you'll have to do some reading in its help file in order to
figure out how to accomplish the actions suggested in the KB article.

Also, it probably would help if you identified all of the processes that
have been running during your "hours of fairly heavy activity." Perhaps
someone here will recognize one of these as known to cause memory leaks.

Thanks for your suggestions. I think this is exactly what I need (i.e. a
performance monitor of some sort) to see what's going on.

But where is the Performance Monitor??? I don't think they're talking
about the Task Manager as it doesn't seem to have the facilities
referenced in the article.

The article says it applies to NT and 2k but doesn't mention XP.

Does XP have a Performance Monitor? Where is it?

Thanks, Frank

I'm not at my XP box right now, but (a) XP definitely has a performance
monitor (I checked it out just before I wrote the last post) and (b) look in
Start > Help & Support for "performance" and you should get a "click here to
open" link. Or, you could just try start > run perfmon.exe <enter>

Help & Support for "performance" and you should get a "click here to
open" link. Or, you could just try start > run perfmon.exe <enter>

Right on! run perfmon does the trick as does finding the topic in Help &
Support.

I'm going to play around with the tool and see if I can make some sense out
of it.

Many thanks, Frank
