I initially ran across this bug while trying to figure out why my cron
was segfaulting repeatedly. My logs looked like this:
Nov 14 06:37:01 deodand kernel: [4036025.234318] cron[4620]: segfault at
b7ed4ff4 ip b7f0f004 sp bfe2ab47 error 7 in ld-2.9.so[b7f0f000+1c000]
Nov 14 07:17:01 deodand kernel: [4038425.336220] cron[4622]: segfault at
b7ed4ff4 ip b7f0f004 sp bfe2ab47 error 7 in ld-2.9.so[b7f0f000+1c000]
Nov 14 08:17:01 deodand kernel: [4042025.486637] cron[4631]: segfault at
b7ed4ff4 ip b7f0f004 sp bfe2ab47 error 7 in ld-2.9.so[b7f0f000+1c000]
Nov 14 09:17:01 deodand kernel: [4045625.639018] cron[4634]: segfault at
b7ed4ff4 ip b7f0f004 sp bfe2ab47 error 7 in ld-2.9.so[b7f0f000+1c000]
The key observation is that ld-2.9.so is no longer installed. This
therefore is bug #551885. The immediate fix is to restart the affected
daemons (which is at least cron and at, but could include others).
Rebooting is one way to do this.
I'm adding this to #484122 so that anyone who encounters it will know
where to look next (I had to do some additional searching).
