It looks like you dont have himem properly configured in your kernel. You should be able to get a heap of 4GB - the java vm internal memory etc so i would say at least 3.7GB on a bad day. I would check how you have your kernel configured. The kernel may also not be seeing all of your memory, this is easily fixed by passing the mem=** option to the kernel, this is documented in the linux kernel source (normally /usr/src/linux/Documentation). This should point you in the right direction Tom - -- Email: [EMAIL PROTECTED] || Jabber: [EMAIL PROTECTED] Homepage: http://www.doc.ic.ac.uk/~tb100 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.0 (GNU/Linux) iD8DBQE9pS7ZXCpWOla2mCcRAq5gAJ4xWkKUQGlvr8DtSZHtmH5uq8qlMACdFaI7 bw7uZ/o0acyRyzEnLbqQWvs= =XTGG -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
