Handle / Semaphore Leak?





------- Additional Comments From niededir@gmx.de  2004-10-24 10:00 -------
Yesterday I made a comparison of Java 1.4.2_06 and 1.4.2_05 with Cocoon2.1.5.1 
and Tomcat 5.0.27.
With 1.4.2_06, I tested different Xmx and Xms settings.


   VM         Time   Handles  RAM       VM-Args
------------------------------------------------------------
a) 1.4.2_05:   8h    5579      45Mb     -Xmx300m
b) 1.4.2_06:   8h    5179      46Mb     -Xmx300m
c) 1.4.2_06:   8h    44522    336Mb     -Xms300m -Xmx1000m

Sometimes there was no increasing for a while (e.g. 15min) and after this pause 
it was increasing again. The test b witch seemed to be stable at 3500, now is 
at 5179.

Today I tested Cocoon 2.1.6dev using Jetty:

   VM         Time   Handles  RAM       VM-Args
------------------------------------------------------------
d) 1.4.2_05    4h    12461     69Mb    
e) 1.4.2_06    4h    12101     59Mb

There are no differences between the Java-Versions. Test b and c looks like 
that the -Xm* settings are deciding about the speed or/and the amount. That's 
the behaviour described by Michael Straessle. I have no idea why test d and e 
has the double of amount at the half of time compared to a and b. I am sure the 
default -Xmx is lower than 300m. 

Can anybody interpret/comment these results?
