webMethods Knowlegebase : Nerv loses events after com.terracottatech.frs.recovery.RecoveryException. (1785032)

Problem

NERV fails to deliver events when the NERV cache is corrupted.

When a NERV application sends events, depending on the delivery quality of service, the events first go through EhCache and get persisted to the local disk.

If EhCache cannot be successfully initialized when you start the runtime, NERV cannot deliver any events. Additionally, NERV does not log an error and does not throw an error back to the application.

sag-osgi.log shows:

net.sf.ehcache.CacheException: com.terracottatech.frs.recovery.RecoveryException: Recovery is incomplete for log /sag/MWS_default/cachedata/nerv.caches/persistence/cachedata. Files may be missing.
