Hi Tommaso,
Yes, you should care. These sites are not joining your cluster as they cannot login. Could you tell me what version the sites that are getting the errors running?

ciao, coming back to this, a few months later (on 4.2.3)
i still see TONS of

in cmsd.log
not sure it has any bad effect ... but: should we care?
this is at least 1 Hz, and comes form multiple sites ....

Hi Tommaso,
You mentioned that the fnal.goc addresses are worer nodes. Why are they connecting to the cmsd?

By the way, yesterday i upgraded the eu redir to 423. Seems to work fine,
even if the statistics is less than 1 day for the moment....

the fnal.gov address is from a WorkerNode (probably running a CMS job).

Hi Tommaso,
What are fw-nat-inside-outside.gridka.de and cmswn2148.fnal.gov? The
message clearly shows that whatever they sent over was incorrect. Yes,
4.2.2 would crash in this case, sigh.

ciao, another piece of info which might be interesting:
I was looking into the bari eu redir, which uses xrootd
xrootd-4.1.1-1.el5

apparently, we did not notice since 4.1.1-1 does not crash as 4.2.2, but
moves along ...

Well, but: isn't th global redir only subscribed by regional redirs

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:
http://xrootd.org/doc/dev42/cms_config.htm#_Toc405927050
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
