Hey all,
Can anyone share any experiences with web application autofarming on the
Tomcat 5.5 cluster.
Is it reliable? Do you use it for production purposes? How big is the
cluster?

Respected friends of the list, I am specifying Cluster nodes (hosts) to use
with tomcat 5.5.9 with an apache server as dispatcher.
In the specification of the disks I have doubts because the new disks SATA has
great performance and speed and with cost comparative minor to the SCSI Disks.

you would need to write a component that queries the cluster classes
(internal tomcat components) yourself.
I believe you can reach the cluster object through JMX and through the
tomcat classes (host etc)

I have two machines running Tomcat 5.0 with java 1.4.
Both are clustered together.
Every once in a while, one or the other just starts spinning out of
control and clocking wall time.
This is on hp ux version 11. New machines, lots of resources (16 Gig
of RAM)
Any ideas?
Thanks,
Micky
Are you using apache in front of tomcat?
Have you done thread dumps when in a good state vs a 100% cpu state? Sounds
like an inifinite loop.
