I have been experiencing an annoying problem with serving large files through lenya, more specifically with DKP Log Parser’s download page. The problem manifests itself as an http error while downloading a file, resulting in an aborted download and a 0 length file being downloaded to the client. It appears rather random, some times the downloads work fine, some times they don’t. Restarting tomcat usually helps though, so I’m suspecting that the problem is caused by some buffer’s memory running low.

I have been unsuccessful in finding a solution despite searching for one. Today I however found a possible solution, it seems to work so far at least.
