Rails keeps increasing memory steadily

Question

I'm using rails 2.3.2 with ruby 1.8.7 and nginx passenger. This application is a RESTful API which serves around 700 requests per minute. Everything goes fine except the memory consumed is growing from 55 Mb to 120 Mb (1 day after).

Do I have to restart those instances every week? I wonder other people facing this problem as well? Or something wrong with this application?

Any suggestions?

You need found where is you memory leak. After this first day, the memory still growing or stabilize ? — shingara, Jan 27 '11 at 09:08

Try using REE (Ruby Enterprise Edition) instead of ruby 1.8.7.

It uses 33% less memory on average, and is 100% compatible with 1.8.7. Without looking at the code, it sounds like a garbage collection problem, which REE + passenger might be able to solve.

From what I've heard, ruby 1.9.2 has a lot of the same enhancements, but switching an app over to run on REE would probably be a lot easier than upgrading to 1.9.2.

Does most rails apps increase memory all the time like this? – Chamnap Jan 27 '11 at 10:32
I don't think so. But then again, you are using Rails 2.3.2, which is quite dated now. Its impossible to say what the problem is without looking at code, so theres only 2 suggestions I could give: Use REE, or upgrade to Rails 2.3.8 (which should be quite painless) – ndbroadbent Feb 01 '11 at 09:18
