Hello Pascal, I think you should ask your question in the ehcache support list, since your stacktrace shows that the problem is in their code.

Hi all, our web application which is an add server (Java 1.5, Apache2 worker mpm, Tomcat 5, mod_jk, on Debian) is using ehcache 1.2.3 to cache data. All was ok since we deploy a new feature which is occasionnaly cpu consuming. This feature slow down the server for few seconds. After this slow down, Tomcat stay at 100% CPU and Apache then is overloaded. By dumping the JVM, I can observed many (around 200) threads waiting for monitor and waiting for lock: "TP-Processor91" daemon prio=1 tid=0x8a8e8b48 nid=0x1c05 waiting for monitor entry [0x88e12000..0x88e130c0] at net.sf.ehcache.Cache.get(Cache.java:653) - waiting to lock <0x91607ce0> (a net.sf.ehcache.Cache) at net.sf.ehcache.Cache.get(Cache.java:631) ... This occurs (only) each time I use this cpu consuming feature. Any idea ?
