Matt,
Do you have any bderror html files in
WEB-INF/bluedragon/work/temp/rtelogs that correspond to these errors? If
you do, I'd love to take a look to help debug the problem.
Thanks
Andy

Hi there. Our web application is on CentOS Linux 5.9 and we are using
Apache, Tomcat, MySQL, and OpenBD. Unfortunately I can't find where
to tell what version of OpenBD we're currently on. Our application is
very AJAX-intensive (hand-written in JavaScript, no JSON), and at peak
hours we receive several dozen web requests per minute. Over the past
few weeks we have been receiving more and more complaints of random
errors with increasing frequency. It has been incredibly hard to
duplicate these errors since they seem to follow no rhyme or reason
and can happen anywhere on the site at any time. We also receive
complaints about the pages often running very slow even though their
and our network connections seem perfectly fine. I have finally
observed that many of the errors coming from Ajax simply report
"NetworkError".
We noticed our Bluedragon logs were filling up rapidly (25 mb) with
tons of...
11/06/13 14:26.46: Error decoding CLIENT data:
java.lang.ArrayIndexOutOfBoundsException
So in bluedragon.xml (never could get the administrator to work on
this build for some reason), we changed our <clientstorage> from local
to our datasource, and that stopped these errors. However, the
problems for our clients have only continued to grow. I did a netstat
on our server, and we seem to have about 70 or so of these from
various IP addresses...
tcp 0 0 www.ourwebsite.net:https
<http://www.ourwebsite.net:https> (ip address):17168 TIME_WAIT
I'm not sure if that is a lot or not, but our current reigning theory
is that the connections are maxing out and not clearing fast enough.
That would at least explain the random nature of the network errors.
I found a post about Tomcat where someone mentions solving a similar
issue by changing the following...
1) Changing the maxWait parameter in the context.xml file to "15"
(15sec) to remove the closed connection.
2) Changed the removeAbandonedTimeout to "15" from 60 to lessen the
time that the closed connections are removed
3) Changed the timeBetweenEvictionRunsMillis from 180000 to 900
However, I cannot find these fields in
\\opt\openbd\tomcat\conf\context.xml
<file://%5C%5Copt%5Copenbd%5Ctomcat%5Cconf%5Ccontext.xml>. I can't
find them anywhere. Can someone please help me figure out where to
change these values or offer other suggestions of what might be wrong?
