Thanks for your help! > There's an overflow bug in format_k2 in 3.5b12 that means that top can corrupt the SIZE field of processes which allocate 2TB or more of memory; that seems to be fixed in 3.8b1 but I've noticed that if a process allocates over 2TB then it doesn't show up at the top of the display when sorting by SIZE in 3.8b1; I suspect there must be another overflow somewhere. I'm sure it'll be a good few years before anyone actually hits this bug running real programs, but I don't know if it might affect other things. -- Bruce Cran [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAklK6AUACgkQn4uvqcJsLfgJ6ACgoc4dDhvlkCIKiHk9T2sHQqNU KtQAnjzOoBU2IC8zb0rcBRQTY+Vw+Yn4 =YRP3 -----END PGP SIGNATURE-----help
