I've posted my abend logs in the abends forum.

I fear I have a problem with LIBC with SP8. I can't see any updates for
LIBC that work with SP8, and not really sure I know what to do.

LIBC appears to have problems with unlocking the database during a
dsrepair. At first I thought this was an issue with 8.8 in my tree, but
I am open to suggestions.

If you want to see my abend log feel free in the abends log.

I'm just looking at my options. I haven't updated any LIBC updates and
went straight to SP8 thinking this would resolve all those issues, but
am open to suggestions.
