[Zope] Number of Zope process on Linux

[Ulrich Wisser]

Hi,

sorry for the delay. Urgent business trip.

after several days of running zope my linux box says:

top:
21800 zope      25   0  2212    4     0 S     1.5  0.0   6:13   0 python

ps:
21800 ?        S      0:00 /home/zope/bin/python /home/zope/z2.py -Z1 
-t5 -X -w8080 -M /home/zope/var/bigm.log -l /home/zope/var/event.log
21801 ?        S      6:15 /home/zope/bin/python /home/zope/z2.py -Z1 
-t5 -X -w8080 -M /home/zope/var/bigm.log -l /home/zope/var/event.log


Any idea why zope won't spawn more threads?

I have zope running on several servers but never had any problem like that.

> It may be that you are seeing only 2 processes right after starting Zope. The additional processes that handle requests are not spawned until the first request happens. I am not running ZEO, so I see 1 process until the first request (with ZEO running that may be why you see 2). Right after restart it looks like this:
