Each single core job that starts has a 'ulimit > -v' of 4,000,000 . Hmm. Does this mean that Hotspot should call getrlimit(RLIMIT_AS) and limit itself to some fraction of that value if it is not unlimited? -- Florian Weimer <fwei...@bfk.de> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99
