Two threads waiting on a object Monitor

[pandiri]

Hi,

Two threads seems to be in WAITING indefinately(VisualVM shows 100% Waiting)..
The following is a block from thread dump


"EventWriter-2" daemon prio=10 tid=0x00007f7764b54800 nid=0x33c5 in Object.wait() [0x00007f7762442000]
java.lang.Thread.State: WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
- waiting on <0x00000006895bc720> (a it.gotoandplay.smartfoxserver.lib.ChannelQueue)
at java.lang.Object.wait(Object.java:502)

"EventWriter-1" daemon prio=10 tid=0x00007f7764324800 nid=0x33c4 in Object.wait() [0x00007f7762543000]

at java.lang.Thread.run(Thread.java:636)

These are the only 2 threads that are accessing the corresponsing object.

Can 2 threads waiting on same object monitor ?.
Can somebody help with what could be the issue here and what should be done ?

Thanks..
