patchlevel 230 was one of the bad ones.  It leaks like a sieve.

See [ruby-core] thread:

[Ruby 1.8 - Bug #216] Memory leaks in 1.8.6p230 and p238
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/17571

It affected a whole range of patchlevels:

Also, a leak of similar severity was introduced later on, starting
in p296 lasting at least through p355:

[ruby-core:22582] Re: [Bug #1223] Memory leak reintroduced in 1.8.6 branch?
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/22852

I'd recommend trying the recent official 1.8.6 release, p368
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/332578

I have not personally tried p368 on my long-running servers, as
I had already found a stable version, p279.  So I have not had a
need to upgrade the version.  I can say that p279 is very stable
in its memory profile.  I'm guessing the official p368 release
probably is too.


Hope this helps,

Bill
