The problem is intermittend and we are not able tho reproduce it as we like.
At the moment the db_verify returns no error.
Maybe the output of db_stat -CA will give a clue?
db_tool db_stat -CA

Hello
We run into serious problems with OpenPKG 4.0.2 and 4.0.7 on solaris
10 SPARC in solaris whole rooted zones.
After some days of normal operation our rpm db gets corrupted.
(aside)
Corrupted means data loss or integrity failure technically
(although its quite common to hear corruption applied
to Berkeley DB with other meanings.)
Is there data loss or integrity failure? Running db_verify
cd /var/lib/rpm
db_verify Packages
against Packages or other tables (Berkeley DB calls
tables databases) will detect integrity failures.
Data loss can be detected by, say, counting the number
of packages installed like
rpm -qa | wc -l
We see hanging processes from the the openpkg rc facility.
The openpkg rc script tests the rpm db with a openpkg rpm -q
openpkg query.
These queries hang up.
Hang up how? Can you add -vv to a query? There is also
cd /var/lib/rpm
db_stat -CA # -- -CA displays all info, -Cl displays lock info
Note that you MUST use db_verify/db_stat for the same version of
Berkeley DB used by RPM. The tools for the same version of Berkeley DB
if internal
to RPM are released with RPM.
When this happens the permission of the rpm lockfiles RPM/DB/__db.001
.002 .003 changes to root.
An rpmdb is protected by permissions on /var/lib/rpm.
The associated __db* files are created as needed.
I would expect root as owner typically, because /var/lib/rpm is
usually writable only by root, and rpm installs are typically run as
root.
But the openpkg wrapper appears
