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

Before tweaking Passenger, make sure everything else is OK. Perhaps put  
the trace on Pastie or something so we can see it?

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.
