Re: [OPEN-ILS-GENERAL] Z39.50 import in 2.12.4 throws errors

[Linda Jansova]

We have already tried increasing the max_stanza_size and it works :-)! I 
have also added this comment to the bug we have reported: 
https://bugs.launchpad.net/evergreen/+bug/1713324.


Thank you once again, Dan!

Hi Linda:

I have also added this comment to bug $ 1713324 - after our upgrade 
to 2.12.4 from 2.10, which included a reinstall on Ubuntu 16.04 and a 
new ejabberd configuration, we had failures when retrieving Z39.50 
searches with lots of records in the result set.


It looks like that problem was due to bug# 1709710 
 "Default ejabberd 
max_stanza_size can be exceeded when chunking (MARC)XML-heavy 
responses". Can you check on your max_stanza_size and see if 
increasing that helps resolve the problems you're seeing? That will 
help confirm that bug.

It may be a different issue as we have tested Z39.50 search
behavior in multiple Evergreen versions - full description has
been reported as a separate bug:

version where the queries have been okay seems to be 2.12.1
(tested at http://demo.evergreencatalog.com/eg/staff/
, i.e. via web client).

To conduct the tests we have been using stock Library of Congress
Z39.50 server settings.

Maybe some of the changes introduced in 2.12.2 are the reason for
this? Such as a fix that allows boolean fields to be recognized
in queries to the Z39.50 server?

The error appears when the result set is a bit large, it looks
like a timeout issue.

Hi,

We are on 2.12.4 and have been experiencing errors when trying

From the osrfsys.log it is clear that the records are actually

The error looks like this:

Network or server failure.  Please check your Internet
connection to 212.osvobozena-knihovna.cz

If you need to enter Offline Mode, choose Ignore Errors in this

and subsequent dialogs.  If you believe this error is due to a

Any ideas what may be wrong?
