You could try copying the file to /tmp (ie swap/ram) and do a continues loop of checksums e.g.
while [ ! -f ibdlpi.so.1.x ] ; do sleep 1; cp libdlpi.so.1 libdlpi.so.1.x ; A="`sha512sum -b libdlpi.so.1.x`" ; [ "$A" == "what it should be libdlpi.so.1.x" ] && rm libdlpi.so.1.x ; done ; date Assume the file never goes to swap, it would tell you if something on the motherboard is playing up. I have seen CPU randomly set a byte to 0 which should not be 0, think it was an L1 or L2 cache problem. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
