Good day everybody.
We are in the same consortium as Bob, and running 2.3.1 client.
We have been open to the public for about 2 3/4 hours today, and
our primary circ computers are showing 542,750k memory usage and
641,500k respectively on a moderately busy morning.
My staff are not complaining about slowness, but they're using i3
systems with 4GB of DDR3 and Win7 Pro. So nearly new computers,
and all they are using them for most of the time is Evergreen and
three or four firefox tabs...
I will bear this in mind though, because my staff had mentioned
something about slowness a few weeks ago, but I assumed it was
gremlins or a couple of people downloading ISOs on our public
computers at the time..
So perhaps many others are getting the same results, but just
don't notice it often enough for it to be an issue...?
Thanks.
Joe

Hi Bob,
Unfortunately this is not the first time I've heard of issues with
Evergreen 2.3+ and memory management.
Previously, memory problems had been reported sporadically even
while we were on 2.0, but since our upgrade to 2.3 the number of
reports from libraries has jumped significantly. We're still
attempting to replicate / look for the source of the problem, but
it seems (from stories reported) that higher circulating library
PCs are hitting memory issues sooner than other departments.
Alternatively, we've observed that other departments in the
libraries tend to close out of Evergreen on a more regular basis
and doing so sometimes resets Evergreen's memory usage down to a
proper level. At present time, we've asked libraries affected to
institute some sort of regular restarting process to their
workflows to try keeping usage down, but it is definitely still a
problem. It's also affecting only a small subset of machines in
the libraries, so only 1 or 2 circ machines break down while the
others are just fine.
Curious to hear from other Evergreen systems running 2.3 (or
greater) experiencing issues, but if we haven't already I think
it's time we filed an official Evergreen bug on the subject to
track discussion/troubleshooting efforts.

Our two front desk CIRC PC's are:
Windows XP-Pro 32bit Core2 Duo E4600, 2.4GHz, 1024MB PC2-5300
SDRAM, 80gb 7200RPM HD
Purchased August 2008
They worked fine with the previous Evergreen version.
The consortium was upgraded to version 2.3.0 (client also)
November 18, 2012
Staff has been complaining they need to reboot the CIRC PC's as
they get slow, stop etc.
Not being able to talk my way out, I started observing the
problem.
Watching Windows Task Manager, the Evergreen.exe process is not
releasing memory.
At one point it had grabbed over 650mb of ram on our East CIRC
A simple log in /out test showed the client kept grabbing large
chunks of ram.
Also learned another COOL library is having the same problem
with their XP PC's.
It was suggested to try the next client 2.3.1 which I put on a
third PC to test.
This PC was recently rebuilt and not yet in service.
Running the same log in /our test, produced the same memory
grab.
This morning I observed another creeping memory problem in a
static situation.
So I ran the same tests on a Windows7 PC for comparison.
PC is i5-650 3.2GHz 4096MB PC3-10600 SDRAM 640GB 7200RPM HD
Simple Log in / out test
22,404k Opened client login screen
52,272k After login and main screen opened
28,140k After Clicking on X to close main screen
49,448k After Clicking log off
61,412k After log in and main screen opened again
59,024k After Clicking on X to close main screen
59,028k After Clicking log off
71,176k After log in and main screen opened again
68,268k After Clicking on X to close main screen

Simple Static test.
Clicked checkout on tab1
Entered patron card number and clicked submit
Clicked + for new tab and clicked Check In
Clicked + for new tab and clicked Item Status
Made tab2 'Item Check In' active and watched the Task Manager
114,240k at 09:20 AM and started climbing
158,832k at 10:08 AM
126,244k at 10:15 AM Went down since last check
140,060k at 10:24 AM
150,300k at 10:31 AM
154,764k at 10:33 AM
164,732k at 10:40 AM
120,068k at 10:47 AM Went down since last check
153,872k at 11:07 AM
Two main XP CIRC's, during normal check in / out use this
morning
West CIRC East CIRC
326,280k 207,400k at 10:45 AM
343,720k 258,304k at 10:56 AM
379,300k 300,676k at 11:07 AM
Cataloging PC from yesterday (Same specs as Windows 7 PC)
11/30/12 09:44 327,900k
11/30/12 12:16 340,256k
11/30/12 05:21 427,412k
The only solution so far has been to completely exit the client
many, many times during the day.
Our director said Saturday, the East CIRC (Has the most
activity) client took so much ram he had to kill the process.
Suggestions ?
