rpm error ... what does it mean?

[Klaus Steden <klaus.steden@xxxxxxxxxxx>]

Hello,

I've noticed some of my systems now emit messages like this when I'm querying
the installed RPMs ...

[root@gilliam ~]# rpm -qa pwlib
error: rpmdbNextIterator: skipping h#     608 blob size(3740): BAD, 8 + 16 *
il(68) + dl(7444)
error: rpmdbNextIterator: skipping h#     608 blob size(3740): BAD, 8 + 16 *
il(68) + dl(7444)
pwlib-1.6.5-11

... what does that mean, and what could have caused it?

thanks,
Klaus
