Heapsize
Hi!
We're running cocoon on a production server, with great success. We've
been suffering some "out of Memory" errors lately, and having a look at
the FAQ, it tells me to "configure your JVMs maximum heap size setting
to be as large as possible and the same as the heapsize
line in cocoon.properties."
Our server has 1Gb RAM. What would be the JVM reasonable maximum heap
size for this setting?
The default (in cocoon.properties) is 60.000.000, would 512.000.000 be
too much? Any hints?
TIA.

What do you mean "instances of Cocoon"? We have Apache+mod_jserv and
there are approx.:
host:~# ps ax | grep jdk | wc
13 78 1008
host:~# ps ax | grep httpd | wc
35 176 1908
The JavaVM parameters are:
java -Xms256m -Xmx450m
Is this some sort of inconsistency between cocoon.properties and these
parameters?
In these machine there's no other significant software (the DB engine is
in another host), apart from sendmail and ftpd.

How many instances of Cocoon are you running? We have a server that
has one instance running and 512MB RAM, so that's what we set our JVM
for. We haven't reached that amount by far.
As to RAM requirements, take a few evaluations--what else is running on
the machine, how much RAM does it take for them to run comfortably.
Remember, just because the JVM is set to use a max of 512 MB doesn't
mean that it always does.
