It has been noticed that When the application tries to "POST" data using Ajax requests with content length > 29000 (and may be even less), one out of two times, the request does not reach web-server.

Following Other observations were made:

1. After waiting for 10 sec. the request did not reach server. At this point, if I close the browser or press esc key, the request immediately reaches the web-server (Browser believes that request has been aborted).

2. Happens only in Firefox. IE works fine.

I understand the limitations of browser. It would be great if someone can provide me alternative way. Please help me understand the problem so that solution can be designed.


The application is very heavy, we need to deal with data (loaded on browser) for more than 3000 entities.

Try to disable the Firebug extension.

Did you test that in a new profile without extensions or in Safe mode?

Yes, the problem is seen without extensions and also in safe mode. But, I am starting to think that firefox is running low on memeory or CPU.

Without extensions the possibility of failing is 1 in 3. I am still unable to explain why closing the browser or aborting the request can cause the stuck request to immediately reach the server.

Is there a way to collect Firefox logs and post it here ?
