I have this problem: There is one django source which is shared by
multiple apache vhosts. Each instance of django project has its own
settings and .wsgi script. Every vhost's WSGIDaemonProcess runs under
its own unique user.
WSGI apache processes running under their users die randomly. When it
happens, there is massive growth of apache www-data processes. It does
not happen at vhost which runs on another IP addres than other vhosts.
Do you have any idea why processes are dying? Thanks Kamil
There runs, Python 2.5.2 and, libapache2-mod-wsgi 2.5-1~lenny1
