actually we observer a strange behavior on a workstation (WinXP Pro SP3) while using Firefox (Version 10.0.0.2). With Firebug (Version 1.9.1) we can see that requests for js- and css-files have to wait 20 seconds until they are further processed.
There is an application in a local Jboss-instance (localhost: 8080) which is used. In order to troubleshoot the problem we already reinstalled the Firefox, reset the user settings, set the value "network.dns.disableIPv6" in about:config to "true". The last change has resolved the problem for about 2 hours until it appeared again.
Does anyone have an idea what could cause the problem?
Is there a timeout of 20seconds im Firefox which could cause the problem?
Thanks a lot and with best regards
