Usually your DomU OS should make shure that out of memory situations are handled as best as possible, but may be i misunderstand your question at all?... cheers, Niels. - -- Niels Dettenbach Syndicat IT&Internet http://www.syndicat.com -----BEGIN PGP SIGNATURE----- Version: APG v1.0.8 iIEEAREIAEEFAk7VRME6HE5pZWxzIERldHRlbmJhY2ggKFN5bmRpY2F0IElUJklu dGVybmV0KSA8bmRAc3luZGljYXQuY29tPgAKCRBU3ERlZRyiDczNAJ9LufizCkgo BCJzZ4+r4YOtR3hTdQCffyt7lBGNEAgI6D4Bssam4ewVmAQ=AP0m -----END PGP SIGNATURE-----
