[Condor-users] DC_AUTHENTICATE: attempt to open invalid session

[Liam Gretton <L.Gretton@xxxxxxxxxxx>]

Hi,

If the central manager is restarted, one particular submit/exec host 
doesn't recover, and the collector logs on the CM give lots of 
"DC_AUTHENTICATE: attempt to open invalid session ..." messages, 
presumably due to the failing host. It won't recover until Condor is 
restarted on the client. Other clients recover from CM restarts without 
any problems.

I'm now running 7.0.4 on all the systems. The failing system is an IA64 
box with 8 cores, and it's running the IA64 RHEL3 dynamic build of 
Condor on Red Hat EL 4. The CM is running CentOS 5.2 and is running the 
x86_64 dynamic build.

Any ideas what causes this and how it can be remedied?
