After I fixed sys/compat/linprocfs/linprocfs.c to always produce cpu%d line(s) my oracle started to behave again. I am not sure if this is actually linux_base or linux_devtools related or if this affects fresh Oracle installations. >How-To-Repeat: please see above >Fix: --- linprocfs.patch begins here --- --- sys/compat/linprocfs/linprocfs.c Wed Dec 1 23:34:43 2004 +++ sys/compat/linprocfs/linprocfs.c.new Wed Jan 5 13:38:33 2005 @@ -426,13 +426,12 @@ T2J(cp_time[CP_NICE]), T2J(cp_time[CP_SYS] /*+ cp_time[CP_INTR]*/), T2J(cp_time[CP_IDLE])); - if (ncpu > 1) - for (i = 0; i < ncpu; ++i) - sbuf_printf(sb, "cpu%d %ld %ld %ld %ld\n", i, - T2J(cp_time[CP_USER]) / ncpu, - T2J(cp_time[CP_NICE]) / ncpu, - T2J(cp_time[CP_SYS]) / ncpu, - T2J(cp_time[CP_IDLE]) / ncpu); + for (i = 0; i < ncpu; ++i) + sbuf_printf(sb, "cpu%d %ld %ld %ld %ld\n", i, + T2J(cp_time[CP_USER]) / ncpu, + T2J(cp_time[CP_NICE]) / ncpu, + T2J(cp_time[CP_SYS]) / ncpu, + T2J(cp_time[CP_IDLE]) / ncpu); sbuf_printf(sb, "disk 0 0 0 0\n" "page %u %u\n" --- linprocfs.patch ends here --- >Release-Note: >Audit-Trail: >Unformatted:
