Hi Jérôme,
I.
Yes, I clean memcached (restart) when I restart my CAS (on my
workstation) for testing purposes.
In debug mode, I can see what ticket is not well decoded by Kryo.
I dumped one from memcached here :
vincent@dgs-12-5912:/tmp$ telnet localhost 11211
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
get
TGT-7-SuxCe4TvaSKxzzpHloAlfqJtFar1L5ziWJwbK1xgAVP5vmzPTb-cas.univ-rouen.fr
VALUE
TGT-7-SuxCe4TvaSKxzzpHloAlfqJtFar1L5ziWJwbK1xgAVP5vmzPTb-cas.univ-rouen.fr
0 599

END
So maybe there is an issue with KryoTransacoder and
LdapAuthenticationHandler on 4.1.1 ?
II.
We updated our CAS production server to CAS 4.1.1 with success here today.
I simply disabled kryoTranscoder in ticketRegisry.xml and there is no
more errors now.
I must admit however that the cpu load was near 100% again ... I found
the error cause inspecting java threads. In fact I wrote an horrible
regular expression as a serviceId in a RegexRegisteredService bean ... :
^https?://([A-Za-z0-9_-]+\.?)*-test\.univ-rouen\.fr(:[0-9-]*)?(/.*)?
I removed it and our CAS 4.1.1 works very well now :-)
Thank you for your help and have a nice WE,
Vincent.

Hi,
Based on the logs you sent me privately, I see a lot of
ClassNotFoundException. I would recommend cleaning the whole cache
(restart memcached) before upgrading the CAS server: old TGT may not be
deserializable by the CAS server v4.1.
Thanks.
Best regards,
Jérôme

I'm using kryo-3.0.2.jar and kryo-serializers-0.35.jar
Actuallay this version comes with cas-server-integration-memcached 4.1.1
(see dependency hierarchy in attachment).
Thanks,
Vincent.
