Anybody else having to restart mongrels because of steady memory growth?
We're running Rails 2.1 on Ruby 1.8.6-p114. Our mongrel_rails processes keep growing slowly, but steadily. We're running 14 mongrels with 1.7 GB RAM, so when a mongrel starts to use over 100MB we're getting tight on memory.
The process starts out with 45MB, goes to 60MB quickly, then slowly keeps growing, about 2MB per hour (about 5 req/min for each mongrel, not much load).
Anybody else have this problem? Anybody running without any memory increase?
What are the characteristics of the app. Does it use send_file? Also check your rails log file (production.log if you're running in production mode) for errors. Which brings up another question: Which mode are you running rails in, development or production? Are you using RMagick or other gems?
