I am running into a problem where Zope is trying to open too many file descriptors (256) in order to process a POST. I'm not sure how to phrase this question, but my reading has suggested that this limit may be set by the FILE struct in /usr/incldue/stdio.h. Does anyone know if this is used in Python/Zope? My first impression was that this problem would be easy to solve -- just up the number of FD's, but now, I'm not so sure. Any suggestions? Here's a traceback -- but I don't think it's much help Traceback (innermost last): File /u05/ilocal/opt/Zope-2.4.0-src/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /u05/ilocal/opt/Zope-2.4.0-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /u05/ilocal/opt/Zope-2.4.0-src/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /u05/ilocal/opt/Zope-2.4.0-src/lib/python/ZPublisher/Publish.py, line 136, in publish File /u05/ilocal/opt/Zope-2.4.0-src/lib/python/ZPublisher/HTTPRequest.py, line 405, in processInputs File /ilocal/lib/python2.1/cgi.py, line 517, in __init__ File /ilocal/lib/python2.1/cgi.py, line 606, in read_multi File /ilocal/lib/python2.1/cgi.py, line 519, in __init__ File /ilocal/lib/python2.1/cgi.py, line 616, in read_single File /ilocal/lib/python2.1/cgi.py, line 636, in read_lines File /ilocal/lib/python2.1/cgi.py, line 723, in make_file File /ilocal/opt/Zope-2.4.0-src/lib/python/tempfile.py, line 155, in TemporaryFile OSError: [Errno 2] No such file or directory
