When I start zope on a Linux system (./start from /usr/local/doc/Zop... directory), I get an error report to the effect that the statement open(PID_FILE, "w") statement in z2.py has failed. Permission error.(errno13). I do have the var directory with the correct permissions - I can login as the Zope user and create the Z2.pid file. What else should I check? Thanks for your help.
