Re: [cas-user] CAS 5.1.6 TGT is destroyed early - but only during high volume

2018-01-18 Thread Ray Bon
Duane,

Is the problem the total number of logins or the rate of logins?
Could ehcache be 'filling up'?
I seem to recall that ehcache can be configured with a maximum cache size.

We are using these defaults, which work with TGT persistence up to two hours,  
but only during medium to low volume login periods.

cas.ticket.tgt.maxTimeToLiveInSeconds=28800
cas.ticket.tgt.timeToKillInSeconds=7200

We also get a TGT TICKET_GRANTING_TICKET_DESTROYED as the new login 
authentication is processing.

Any ideas on possible mis-configurations areas, or how to best debug this?
