Hi All,
Today we tried to update our production CAS server on 4.1.1 version.
But we failed and we went back to our 3.5.2.1
After starting, the CAS answered correctly and I logged in to my webmail
(proxy cas) successfully for example.
But the CPU charge was 100% and we had errors like this (we don't have
the stack trace, I don't know why ...) :
org.jasig.cas.ticket.registry.MemCacheTicketRegistry] - <Failed fetching
[PGT-************************************************cEQOZjuIUV-cas.univ-rouen.fr,
java.lang.RuntimeException: Exception waiting for v
alue] >
We also got a crash of the JVM (!) :
"""
# Problematic frame:
# J
com.esotericsoftware.kryo.serializers.ObjectField.write(Lcom/esotericsoftware/kryo/io/Output;Ljava/lang/Object;)V
""""
We enabled some features on this CAS 4.1.1 - we set up memcached like
described on the doc - so we used kryoTranscoder :
http://jasig.github.io/cas/4.1.x/installation/Memcached-Ticket-Registry.html#object-serialization
So I think we will retry to update our CAS on 4.1.1 in production but
without using this kryoTranscoder (on our 3.5.2.1 we're using memcached
without kryoTranscoder)
Thanks for any ideas/advices about that.
