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. Only ulimit -s unlimited seems to work for my setup.
To clarify, I have had this problem with R-2.4.1 -> R-2.7, so I am inclined to think it is not 2.7-specific. The oldest version that worked without messing with stack usage limits in the shell was R-2.2.1. -----Original Message----- From: Laurent Gautier [mailto:[EMAIL PROTECTED] Sent: Monday, July 14, 2008 8:40 AM To: Toby Hocking Cc: RPy help, support and design discussion list Subject: Re: [Rpy] rpy and mod_python problem Thanks for posting it. I am not a C stack expert, but I suspect that there is a reason why it is not unlimited by default. I would particularly consider putting somehow a limit to it on a webserver, although that limit would naturally be larger than the default one. It would be nice come up with such a number a put it in the documentation for the time being. >From what I read, it seems that from version 2.7 R is more C stack-hungry. May be this will improve in time. I have started playing with threading in python with rpy, and the C stack problem appears. Toying with the stack limit again let things run properly. Are there win32 folks here having similar problems with the C stack ? 2008/7/7 Toby Hocking <[EMAIL PROTECTED]>: > Hi all, > > Just thought I would post with a solution I have found to my own problem. > > I was getting an error: C stack size is too small (I think from R) in my > shell, so I told my shell (bash) ulimit -s unlimited, which makes the C stack > size unlimited, and that fixed the problem, so I can use R-2.7 with rpy and > Apache2/mod_python/Django. > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Toby Hocking > Sent: Wednesday, June 25, 2008 9:29 AM > To: RPy help, support and design discussion list > Subject: Re: [Rpy] rpy and mod_python problem > > > I'm inclined to think that it is NOT an inherent incompatibility problem with > mod_python and RPy since I have a working Rpy/apache/mod_python system on top > of Django.
