Hi, I've a tinderbox which uses tmpfs to build ports. Every time I build a port which executes linux ldconfig it results in an unkillable process which uses 100% CPU. The problem is reproduceable without tinderbox: # uname -a FreeBSD daedalus.network.local 9.0-CURRENT FreeBSD 9.0-CURRENT #3 r216761: Tue Dec 28 15:32:26 CET 2010 root@daedalus.network.local:/usr/obj/usr/src/sys/GENERIC i386 # mkdir /compat/test # mount -t tmpfs tmpfs /compat/test # cp -Rp /compat/linux/* /compat/test/ # mount -t linprocfs linprocfs /compat/test/proc # /compat/linux/sbin/ldconfig -r /compat/test/ # pgrep ldconfig 3449 # procstat -i 3449 | grep KILL 3449 ldconfig KILL --- # kill -9 3449 # procstat -i 3449 | grep KILL 3449 ldconfig KILL P-- >From top(1): PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 3449 root 1 44 0 992K 712K CPU1 1 10:06 100.00% ldconfig When I reboot the machine it hangs after "All buffers synced.". I've uploaded some additional output of procstat and ktrace here: http://people.freebsd.org/~beat/logs/linux-ldconfig-tmpfs.txt Anyone knows how to fix this? Thanks, Beat
