PSAdump problem

[alebello]

I'm having some troubles in migrating to another server 200 domain names. PSA is version 7.5.1 on Fedora Core 1
I run /usr/local/psa/bin/psadump -F -z -f /dump.gz --nostop and then psadump seems to freeze at "Checking packages installation"
Is there anything I can do ? It's more than half an hour it's running...
Best regards
