I understand you want to avoid deploying kdump, but you should focus on saving your console history somewhere. It will be difficult to help without the panic message.

For 2.10, maybe I was a bit optimistic. I think you should be able to build the RPMs from sources, but pre-build packages are not available.

    a running ssh shell only shows
    kernel panic - not synced.
    No trace, nothing. I will try to capture the console next time that happens.

    yes.. though not deeply. Was difficult, as kdump is not installed on
    that one and I was a bit afraid to deeply touch the system as we bought
    it pre-installed and the kdump-tools are not installed and /var/crash is
    empty, so I fear kdump was not configured :-( So my only knowledge is
    that the kernel panics :-(

    not easily, the system is always full and enforcing group quotas was our
    way so far to keep the system from physically reach 100%. But of course
    we could talk to the users and ask them to behave nicely.

    That would be great!!!!!! Where do you find the server RPMs for this
    version? I couldn't find them on whamcloud:
    only contains server RPMS for el7 as far as I can see.
    Thanks again
