No it's not a local problem. It's a Jonas problem.
In fact you need to execute quite often (in a cron) the command line:
jonas admin -passivateWhen you do so, you don't need to restart your server… And this will remove your exception.
To optimise your server, you should optimise your database. For that just execute the command line:
vaccumdb -f databaseNameIn order to allow Jonas to use more memory than only 128Mb you should set the system variable JAVA_OPTS="-server -Xms768m -Xmx768" depending the amount of memory you have on the computer. You should set 2/3 of the physical memory.
