this is a sporadic issue and we are not able to pinpoint the cause..(what code , etc) . We have the following code in the xhtml files -

<rich:tabPanel switchType="ajax">
----
<rich:tab label="Diam Realm">
--------
</rich:tab>
--------
<rich:tab label="Diam App">
-------
</rich:tab>
</rich:tabPanel>

then at least you could try to update.. it's really difficult to tell about the reason according to the description and talking about old version.
