Rails - Jul 2007 - stack level too deep when parsing xml

I''m trying to figure out why I''m getting a stack level too
deep error.
I have controller which parses xml (about 1400 lines) and ingests it
into mysql.  First I was getting a system stack error every time, but
then I found the ulimit -s command which allows me to raise it from 8mb
to 64mb.  That solved the problem I thought,


But now, I can parse the xml once, but when I do it for a second time, I
get the stack level too deep error.  If I quit the server (mongrel) and
restart it using the script/server call, something resets and lets me do
the xml parsing once again.  But only once.


is something getting clogged up?  Do I need to clear the stack level
somehow?

It''s not an infinite loop, just a long xml file.

Sounds like you have something, maybe a variable, that references
itself causing an infinite recursion?  Maybe it gets defined the first
time around, so it''s not recursive until the second time?  Just a
guess.

Nope, that''s not it.  If I take out the @database.save line which 
creates the sql insert statements, I can run it as many times as I like 
no problem.  Somehow 1400 sql insert statements brings rails to it''s 
knees and it cant recover without a restart.  This can''t be true? 
There
must be a solution?  Rails must be able to handle this?  No?

Strangely enough I got that error in an app with - in a foldername and
then changed to _ and the error did go away.
