Just a quick call for ideas on this problem we have... Setup: Zope 2.7.5 (~180 sites) -> apache (-> varnish for 1 high profile site) Most noticeable symtoms: Takes 30 sec. or more to serve a page, or times out. Sporadic problem, but allways during general high load. Lasts less than 1 hour. Restarting zope does not help. Lots of apache processes in '..reading..' state Apache accesses and volume is down. Server load is unchanged, and < 2.0 Apache processes is way up (~250 aganinst <40) Netstat "established" connections is WAY up (~650 aganist < 50) Is this zope hitting some sort of limit and just letting Apache hang? Would setting up ZEO on the same box make a difference, or would it be better to extend varnish coverage? What would you do to pinpoint the problem? Any ideas are welcome! Regards Gaute Amundsen
