Well, just for anyone interested, I did a little more digging and there
is an Apache-Weblogic connector that is used and there are settings for
this connector:
http://edocs.bea.com/wls/docs81/plugins/plugin_params.html
The one of interest for those with similar setups is 'WLIOTimeoutSecs'.
The default is 5 minutes, any request that takes longer is considered
timed out and I guess a 503 (?) status is sent to Flex but Flex isn't
catching this and just acts like it's still waiting for a response. I
changed this setting to 10 minutes and the process that was previously
finishing past 5 minutes still takes the same amount of time but Flex
app regains control now because the request hadn't timed out.

Subject: [flexcoders] Flex 1.5 - RemoteObject request timeout
We still support a Flex 1.5 app I wrote 3 years ago that our clients use
to run reports with. I'm in the midst of upgrading the entire app to
Flex 2+, but of course the db people keep adding reports and one
recently added report is for the admin-side only and is a crude report
that can sometimes take over 5 minutes to return from the database with
data.
We have a setup as follows: Apache + Weblogic + firewall + Oracle
database. Here's the weird thing...if only one person runs the report
at any given time...it may take about 4.5 minutes, I see the call made
to the database, I watch the log and see after 4+ minutes, the call to
the stored procedure return to the application server and the original
method return to the front-end and Flex correctly displays the report.
If I open two browsers or have a coworker hit the report within a few
seconds of my initial request and these two requests are made, a.) the
call to the database takes a minute or so longer (I know the db people
need to optimize this, but this is what I'm dealing with up front) and
b.) I see it come back and the data returned to the front-end but the
Flex app on either my or my coworker's machine or either browser
(dependent on how I'm testing) does not get the returned response. The
clock busy cursor just continues to spin.
I've searched the archives and it seems a few people have posted similar
problems but nobody has posted what their absolute resolution was.
Anyone know anything about this? I literally see the data returned to
the Flex application in the app server log but my Cairngorm command
class result/fault handlers never capture anything and the busy cursor
just keeps spinning. Anyone know anything about this or should I make
use of my Flex support contract? Could this be a timeout between the
apache and weblogic layer? I checked with the systems guys and they
claim that the request timeout feature of apache isn't being used but I
don't know if there is a default setting that apache uses...I guess I'll
check that out...but any feedback would be GREATLY appreciated.
Thanks so much for anything!
