Mergerepos command error: Cannot allocate memory/ RPMDB open failed

[rotru at br.ibm.com]

Guy, I have had the following problem frequently.

I'm not sure if I have a memory problem or a rmp db problem.
Has anyone ever seen this ?

I'm running koji on a Fedora 11, with
createrepo-0.9.7-7.fc11.noarch
yum-3.2.23-3.fc11.noarch
rpm-4.7.1-3.fc11.x86_64


$ /usr/libexec/kojid/mergerepos -a i386 -b 
/mnt/koji/repos/oc-fedora12-build/742/i386/blocklist -o
