Nonce cache FileNotFoundException

Hi We are running a CXF secure webservice. This has been running in production for a few months now. We have 6 servers where the same code is running. But we are getting the below error only from one of the servers when a request is posted.

unwinding now: net.sf.ehcache.CacheException: java.io.FileNotFoundException: /tmp/cxf446961026/ws-security%002enonce%002ecache%002einstance-678998632.data (No such file or directory)
