Hi, I am using UML in the following configuration: Host: - vanilla 2.4.22 kernel with skas3 patch - Debian Woody UML: - vanilla 2.4.22 kernel with UML patch, options for honeypot (hppfs, tty logging, monolithic kernel) enabled - rootfs is Red Hat 7.1, installed native and copied (dd) to the image file - Command line is: linux honeypot con=xterm ssl=xterm ubd0=root_fs ubd1=swap fakehd fake_ide ubd=3 eth0=tuntap,,,192.168.0.99 umid=rh71 mem=64M root=/dev/ubd0 tty_log_fd=3 3>log/tty.log When I start top (version 2.0.7 off the Red Hat CD) it shows it's normal display, but when the display update should appear, I get a "floating point exception (core dumped)". Any ideas? Regards Stefan |

I believe this is a bug in top. It is (I think) dividing something by the difference between two times, when those two times are the same. Jeff |

When I comment out the following line in $hppfs->add() "stat" => proc("stat"), top stops crashing. I did a watch -n 1 cat /proc/stat on the UML, but I did not see any weird things happen there that might have caused top to crash. Maybe this is reproducable on other guest file systems (with other versions of top) too? Regards Stefan |

Its more likly a divide by 0 or an overflow of some sort. James |
