Do you have a test script to reproduce the behavior?
I am interested in this patch-tag uses sendfile (via happstack) to
serve static data, and I'd like to know if I'm affected by this.

Hi all,
I've been using the sendfile package off Hackage, but it seems to be leaking file descriptors when using the Linux-native build.
What's happening in my specific case is the following:
1) client requests a range of a file 2) server starts sending the range 3) client disconnects before receiving the whole file
This happens over and over with the client requesting different ranges of the file (so the client does make progress).
If I use the portable build of the sendfile package, everything works fine for hours and hours of this happening.
If I use the Linux-native build of the sendfile package, the server will eventually run out of file descriptors. According to "lsof" the files that are being kept open are the data files being sent in 2) above.
This is on GHC 6.10.x (Ubuntu).
Is anyone else seeing this? Anyone got any idea what's going on?
Cheers,
