Hi Andr�, Thanks for the link to Nico's post! Most of the full GC's are now around 3 sec (max 11 sec), before the changes they resulted in hangs of 10 min or more.
The installation now runs with: -Xmx512 -Xms512 -server -XX:NewRatio=2 -XX:SurvivorRatio=6 Total memory is 1024. The strange thing with the GC is that with this settings the number of Full GCs increases with time and after a some time the installation is only performing Full GC's (see part of the log below). Any idea what this means? > Is OSCache set to a maximum? Does it cache to memory and/or disk? The maximum is set to 1000 and only memory cache is used at this moment. What are your experiences with the settings for OSCache? Kind regards, Henk. T. +31-(0)6-29054903 E.
