CAS 5.3.8 EhCache & DiskStorage Problem

[Artur Stöcklin]

Hi Community

Currently we use the CAS in version 5.3.8. There are two instances which share tickets through the ehcache (version 2.10.5). The CAS gets his property data from the cas config server. The problem we are facing applies to the EhCache disk storage.

Unfortunately the tickets are not saved to disk although disk overflow is configured. I have spent some time with debugging but currently I am not able to find the problem.

The ehcache ticket registry works well in memory but as soon as the memory max ticket size is reached the tickets will be deleted from memory. the configured storage on disk stays empty without any cache file.

here is the ehcache configuration from the cas config server:

</ehcache>

Logfile 1 - set to log net.sf.ehcache

attached as file ehcache.log

Logfile 2 - set to log 

org.apereo.cas.config.EhcacheTicketRegistryConfiguration

org.apereo.cas.config.EhcacheTicketRegistryTicketCatalogConfiguration

org.apereo.cas.ticket.registry

attached as file ehcacheCas.log

Any help would be very appreciated

Many thanks
