Sporadic Posting Problem and 302 Error for in newreply.php

[Logician]

I think there is a some sort of problem in about new reply posting in vb.org:

When I type my reply and send submit in a thread, page usually hangs. I have to go back and redo for a couple of times until it goes through. After it goes through once, following replies usually go fine from now on. But when I'm back to site say a few days later, this starts all over again.

This happens in both quick reply and advanced reply. I experience this in my webtemplate thread but I believe it is not limited to there:

This has been going on for me for a long time and happens in different browsers and computers too. Finally today I tried to catch a hint in this bug after I enabled firebug before my reply. During initial connection of submit reply page, firebug reported 302 error for newreply.php in POST request in 98.158.195.239:80.

After a few times to resending, it went through as usual but as you can tell 302 error is not normal during new reply process.

FYI.

Edit: While creating this thread same thing happened. Here is screenshots I captured in the process:
