Questions: Why did this affect only half of my machines? How could the RPM databases have been broken? The update that seems to be killing them is less-378-7.2.legacy, which has managed to get installed even on two of the broken machines.
Finally, I know the standard thing-to-do is rm -f /var/lib/rpm/__db* and install a more recent version of rpm. But I've already got rpm-4.2-1 on these machines, so those locking issues shouldn't be causing a problem. Besides, the reboot would have done that rm -f as part of rc.sysinit.
Anyone else have this problem with this week's updates? It'd be nice to know that it's not just me.... Other suggestions also welcome.
yep, i saw segfaults and hangs with less on a few of my legacy systems. rebuilddb cleaned it all up.
Talking to others, it's clear that there's some problem with the recent "less" rpm. Here's an example:
# yum -y update Gathering header information file(s) from server(s) Server: Fedora Linux / stable for Red Hat Linux 9 (i386) Server: Macromedia Flash Player for Red Hat Linux 9 Server: Red Hat Linux 9 (i386) Server: Red Hat Linux 9 (i386) updates Finding updated packages Downloading needed headers Resolving dependencies Segmentation fault
Trying again with -d 10 it makes it further: less 100 % done 1/2 while an strace shows it's hung on: futex(0x40ec10d0, FUTEX_WAIT, 0, NULL
That was on a machine that had just finished an "rpm --rebuilddb" just to make sure there wasn't a pre-existing problem.
Another machine died also... I caught it segfaulting with the -d 10: [snip] localhdrpath= /var/cache/yum/redhat-os/headers/macutils-0-2.0b3-24.i386.hdr for macutils i386 localhdrpath= /var/cache/yum/fedora-stable/headers/netdiag-0-2.4-0.fdr.4.rh90.i386.hdr for netdiag i386 localhdrpath= /var/cache/yum/redhat-os/headers/pilot-link095-compat-1-0.9.5-22.i386.hdr for pilot-link095-compat i386 Segmentation fault
Finally, I tried (after again cleaning the rpm database):
# strace yum -d 10 -y update
[really huge snip]
