Hi,

We are sudently facing a critical problem with our production Now.MMS setup.

The service is slow and when sending an MMS, the terminal stays with the "sending..." message and several sending are done.

The MMSCDEBUG.log is full of the following message I never saw before:

HttpChunkStrip: Decoding chunk size 8192

We rebooted the server with no effect.

Please find the MMSCDEBUG.log file attached.

Thank you for your quick feedback

Franck

Hi Franck,

It appears that something is going wrong in your accounting callback routine.

Those odd debug messages are reporting the receipt of 8192 byte chunks of data from your accounting callback. By my rough calculation, the accounting callback is returning about 15MB of data, but it is doing so slowly. The end result is that it takes so long, the sending terminal times out and tries again.

The problem is that the accounting callback is returning a redirect response that I don't think it means to. The long delay is triggered when NowSMS tries to request the redirect URL.

Here's what happens:

NowSMS requests an accounting callback:

http://localhost:18080/MMS/AccountingCallback?Type=MMSRetrieve&From=xxxxxxxxxx&T o=zzzzzzzzzzzz&MessageID=20130114/18/D1C0A11B&Size=565

The accounting callback returns a 302 HTTP redirect to:

http://localhost:18080/MMS/cdrs

NowSMS retrieves this redirect URL but the data returned is very large and takes a long time to process.

I suspect that it was not intended for the accounting callback to return this redirect response.

The accounting callback needs to be fixed or temporarily disabled.

ok, we fixed the redirection page. We use thisbecause it's convenient to check what have been done when testing the webservice.

Thank you for your fast and efficient support!
