Sorry for the long callstack, but...we're getting a segfault running our
pyramid stack under uWSGI on our dev OX machines. Same setup runs fine on
our Suse Linux hosts. It happens every web request on my machine and
intermittently on another machine when running apache perf tests. My
machine has less memory, which might be an indicator, but I still have 1GB
of available ram at least.
We thought maybe it was a threading issue since it is sibtramp, but still
happens with threading disabled.
Our settings:
env = PYRAMID_INI=development.ini
http = :6543
master = true
processes = 1
harakiri = 60
harakiri-verbose = true
limit-post = 524288000
post-buffering = 8192
listen = 256
#max-requests = 1000
#reload-on-as = 128
reload-on-rss = 96
no-orphans = true
log-slow = true
enable-threads = false
virtualenv = ../env
wsgi-file = wsgi.py
touch-chain-reload = ../Common/conf/restart
Googling various versions of this doesn't turn up any useful results.
Anyone have any ideas?
thanks
michael
