EAR redeploy makes ajax failing
Hi
from time to time, we have a really weird error after EAR redeploy : AJAX stops working.
We're using Seam 2.1.2 on JBOSS 4.2.2 (jdk 1.5.018) on a windows 2003 server.
I had a look on http requests initiated by Ajax : they are identical, but the responses are different.
When it works, the ajax response is something as following
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>

</span>
<a id="j_id363:existingRecordNumber:aproachLink" name="j_id363:existingRecordNumber:aproachLink" href="http://127.0.0.1:8095/" target="_blank">Records app</a>
<meta name="Ajax-Update-Ids" content="j_id363:mainTitle,j_id363:existingRecordNumber:aproachLink" />
<span id="ajax-view-state">
<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="j_id4" />
</span>
<meta id="Ajax-Response" name="Ajax-Response" content="true" />
</body>
</html>
After a redeploy of EAR, when ajax fails, the same call gives the following response: \
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link class="component" href="/MyApp/a4j/s/3_3_0.GAMETA-INF/skins/glassX.xcss/DATB/eAGTcz60MXT5DGkAD2IDhA__" rel="stylesheet" type="text/css" />

</span>
<meta id="Ajax-Response" name="Ajax-Response" content="true" />
</body>
</html>
As you can see, the response is almost empty. It handles only an update for the ajax viewState element.
The most disturbing it that stopping JBoss and restarting it (even with a cleanup) does dot solve the issue: when it happens, the only one solution we have is to restart the server ! ;(
Thus, we strongly suspect a problem at OS level, but have to clue : did anyone encountered a similar problem ?
Thx
