While browsing through the collector, I noticed 1515: ZServer Bug: Stack overflow on DEC UNIX 4.0 E | Compiled Python 1.5.2 from source using cc compiler(Configure-d with | option --with-dec-threads). | Compiled and installed from the source zope-2.2.0. | Started zope. | When trying to access the Quick_start or the Management screen | (with superuser and its password) zope stops and a message like | tihs is displayed: | Stack overflow: pid 19902, proc python, addr 0x140929f58, pc 0x12003a790 | About two months ago I got the very same stack overflow, when trying to install Zope 2.1.6 on one of our DEC servers. I finally solved the problem by making the following change to the Makefile, after running ./configure: 146c146 < OPT= -O -Olimit 1500 --- > OPT= -D_REENTRANT -threads Disabling optimization alltogether, i.e. removing "-O" finally made the difference and got rid of the aformentioned stack overflow. Fiddling with stack sizes didn't help in any way, as far as I remember. This is in slight contradiction to the recommendation given by Brian Lloyd in http://classic.zope.org:8080/Collector/1515/view and might hint at the slight possibility that the stack overflow is just a symtom of an optimizaitiion bug in gcc, instead of a too-small stack. Perhaps somebody more knowlegeable about OSF1, alpha and gcc might investigate this further. Personaly, I'm happy with my solution: that specific zope instance has an uptime of 64 days now, and I don't care much about optimization for that not so heavily used internal server anyway.
