AIF read Error executing code: Insufficient memory to run script

Built a custom AIF Service and which was getting invoked from a Commerce Server .Net web service and whenever the read operation on the service was invoked, it goes to non responding state for more than 2 minutes and then gets into the exception block throwing the below error "Insufficient memory to run the script"

Thanks to the EMEA blog which pointed to the right direction http://blogs.msdn.com/b/emeadaxsupport/archive/2009/06/15/error-executing-code-insufficient-memory-to-run-script.aspx

Initially, I added the maxbuffersize to the AOS registry setting but that didn't help, then adding the maxbuffersize to the .Net BC configuration in the registry did the trick and this error got resolved
