I seem to be getting a SystemStackError exception when running Mephisto under Passenger. The trace I get has 149 lines of backtrace, which seems large, but when looking at it I don''t see any loops nor other issues. I think this may actually be hitting a system limit. So, the question is, how do I work around this? Can the stack size be increased using some Passenger knob I was thus far unable to discover, or is this a compile-time option I need to tweak? Thanks, --Michael

Michael, I have been using Mephisto with Passenger and its working great.Try providing the stack trace. Thanks, Kilari.

OK, sorry for the spam here :)
This is when attempting to post a new article, but it also happens in
liquid templates from time to time.
Posting comments works, logging in does as well. This is using a
slightly themed but otherwise stock template in terms of what is in
the template files.
SystemStackError (stack level too deep):
