Re: [OPEN-ILS-GENERAL] Slowness/freezing with XUL staff client

[Chris Sharp]

Jeff,

 a multibranch system with a Linux thin client setup

We have heard of *many* problems with library systems that attempted
running Evergreen in thin clients.  They persisted to the point of most
sites reverting back to bare-metal setups, and since then, we haven't heard
much about it.

Hope that's helpful!

Chris

Re: [OPEN-ILS-GENERAL] Slowness/freezing with XUL staff client

Josh, that's very interesting.  One of our affected libraries makes 
heavy use of patron search for retrieving patrons.  I found a bug report 
in Launchpad about patron search using up RAM:


https://bugs.launchpad.net/evergreen/+bug/1110817

I did a quick test that seemed to confirm the issue; my findings have 
been added to the bug report.  I'll need to do more testing and follow 
up with our other affected libraries to see if they use patron search 
regularly.

Subject: [OPEN-ILS-GENERAL] Slowness/freezing with XUL staff client

Our consortium has a few libraries where the Evergreen staff client 
periodically becomes unusably slow or freezes up altogether.  I'm curious about 
other libraries' experiences with this problem.

1. Does the staff client slow down or freeze up regularly at your library?  How 
often does it happen?  Are there any noticeable patterns (e.g. are only circ 
stations affected, not cataloguing)?

2. How do you deal with the problem?  We usually recommend limiting the number 
of open tabs, restarting the client periodically throughout the day, and 
increasing RAM.

3. If you use the web client, have you noticed an improvement?  We suspect that 
the root of the problem is the ancient version of XULrunner used by the old 
staff client, but we haven't had the opportunity to compare the web client in 
production.

I know of two sites on Windows 7 and a multibranch system with a Linux 
thin client setup.  There may be a couple of others on one or another 
version of Windows.

Having dealt with this same issue over the course of many migrations (but only 
a few weeks and only at the new site...) the OS doesn't matter.

Jeff,

Is there an OS version that this happens on more often?  I'm looking
at you, Windows 10.

Re: [OPEN-ILS-GENERAL] Slowness/freezing with XUL staff client

[scott.tho...@sparkpa.org]

We are noticing a similar and vexing problem at one of our newly migrated 
libraries. The staff client slows and throws a series of "Network not found," 
"String is not a function," and other random errors. We have verified that is 
not a latency problem caused by insufficient bandwidth. They have plenty. The 
PCs are new. No other libraries in our consortium are affected. Any insights 
would be appreciated.

Thank you,
Scott
