I have a Pentaho server 8.1 running and at some random moment, it throws this exception when it's loading one or several dashboards.

"net.sf.ehcache.CacheException: java.lang.ClassNotFoundException: pt.webdetails.cdf.dd.DashboardCacheKey"

I attach the stacktrace. There is any clue to solve this bug?

I figured out a workaround with this bug. I changed the file /pentaho-server/pentaho-solutions/system/pentaho-cdf-dd/ehcache.xml on the pentaho-cde cache by adding the maxElementsInMemory to 5000 and switched the eternal flag to true.

It does help but I'm concerned if this change will cause other unknown issues. Should I be worried?

Hi Jose,

that surely seems like a bug. Could you please create an issue in JIRA ?
