Well, but: isn't th global redir only subscribed by regional redirs (so
not many)?

you're right, I neglected this fact (outsmarted myself ;))...

Probably eu redirs are the most connected, with close to 64 cmsd
entering... It s just normal we saw the problem there.

ok, this is alarming and we should revise current setup and introduce more redirectors if needed in EU. Btw, I recently talked with Andy about this - it looks much more promising way to handle 64 limits - to think about supervisors:

I'm going to do this in transitional federation where there is one global redirector for all T3s and then those subscribers who will be kicked off from production federation and subscribed there instead.

Ifca said it has 336-1, which is fairly common. I guess it cannot be due
to (just) the release....

Andy, did you understand the source of the bad Iogin data? Is it worth
trying and debugging it?

        Hi Tom,

        yeah, that is my guess too, but then we have global redirectors
        at CERN
        running 4.2.2 dealing with hell lot of cmsd subscriptions so I'd
        expect
        some visible trouble there as well. So maybe we're lucky there
        too so
        far... (I believe that autorestart of cmsd if it crashes is disabled
        there, Jan?)


    No, the CMS global redirectors are on CC7, and will auto-restart
    cmsd on "unclean" exit (Restart=on-abort).  I hope that SEGV counts
    as such...

    Not sure whether we'd even notice the occasional restart, unless
    another tool (abrt) picks this up.

    Cheers
