I was mentioning R-2.7 because I stumbled upon posts about stack problem on BSD since R-2.7.
May be it has to do with how many threads is the combo apache/mod_python is using. I think that there is a way to compile mod_python without threads. 2008/7/14 Toby Hocking <[EMAIL PROTECTED]>: > I have tried ulimit -s values of up to 2000000 but even then I get C stack > limit usage errors in R -> error initializing RPy.
