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 ?
