Hi Ciaran, thank you for your hints. I tried with "ulimit -a" and got
time(seconds) unlimited file(blocks) unlimited data(kbytes) 4293918720 stack(kbytes) 392192 memory(kbytes) unlimited coredump(blocks) 4194303 I used "top" for checking the RAM usage. The problem seems to be xercesc depending, because there is enough virtual memory and a background process using 100MB doesn't change the result, it measn, unknow exception when reading xml, when 672-674MB used. Can it be the stack? I am not sure.
