iisnode failed to process http response status line

Question

I'm using IISnode 0.1.21 x64 on Windows 2008 R2 and Node 0.8

My application is running successfully with 4 threads. But after sometime (say 3-4 hours) the responses don't make it from IISnode to the client and the user doesn't get the data on the page (but the rest of the application is working). I tried creating a log in the IISnode folder but didn't get anything from there.

If I remove even one node.exe process from the task manager, the application starts working properly. Then again after a couple of hours, i'm back to square one.

I got the ETW log and this is what it shows:

This condition oftentimes indicates that the connection between node.exe and iisnode was broken in the middle of the application sending back the HTTP response. This in turn may be a result of an exception during response processing. It might be a good idea to check your response code paths for unhandled exceptions, and/or register a global uncaughtException handler to see if any exceptions go unhandled. If that does not help, please open an issue at https://github.com/tjanczuk/iisnode/issues/new.
