I see a lot of threads like this one:
"JMX server connection timeout 6925" daemon prio=10 tid=0x08faf000
nid=0x2759 in Object.wait() [0xac0ae000..0xac0af130]
java.lang.Thread.State: TIMED_WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
- waiting on <0xd5fcec60> (a [I)
at
com.sun.jmx.remote.internal.ServerCommunicatorAdmin$Timeout.run(Unknown
Source)
- locked <0xd5fcec60> (a [I)
