Hello Sterling, Friday, March 14, 2008, 7:06:24 AM, you wrote: yes, it's another question. my own program also writes to logfile and it got lock-free only when i've switched to using my own IO routines
This answer may be way off base, but if differences appear between ghci and compiled versions, I've often found its as simple as remembering to compile with the -threaded flag. The ghci runtime is threaded by default, as I understand it, while compiled binaries are not, and IO operations will block in very different fashions (i.e. in their own thread, or stalling the entire app) depending on the runtime.

web application), I have a log that confirms that the response arrives correctly.
I hate to see any requests for help go unanswered here, but this one might be tough. I think you need to give some more information, otherwise the suggestions are going to be very general. Can you put the Haskell source code on a website somewhere and link to it. Since it's a network service, an example request and reply might be good to include.
In general, you should check that you are correctly flushing your connection. If you are using Handles to interface to the network, they can buffer the response. hFlush[1] may need to be called when you have finished generating it.
