Which means, however, that you should _not_ use the drop-queue feature, as it can happen that your job gets pushed onto a Red Hat 6.2 system rather than a Red Hat 7.2 system.

BRAT was not updated correctly - there, that's said. One should always uninstall the previous minor version, as you can really get into some oddities if you don't, since the minor version number isn't used in the soname. Also, you could end up with a huge amount of old libraries lying around. All the BRAT libraries takes up 23M in total. Anyway, the proper people know this, as I mentioned it several times. The kernel does not unload the shared libraries unles it really needs to, so if you're logged on over an upgrade, the old libraries may be stuck in the cache. A sync will help you. The best way to avoid all these troubles was if we had individual version numbers for each library. However, when we made BRAT 2, I believed that it would easily be forgotton, which would lead to much more confussion. If the sentiment is that it will not, we can chagne it. > The first morale is to read in details the message that come from > RCF, to catch these kind of exceptions I generally read the mails from RCF on these topics (in the form of a digist), but I didn't see any mail that said that rcas0008-12 are running Red Hat 6.2 - I just browsed the archive and found - nothing. > cheer up ditto.
