Hi,
log4j buffer is not getting emptied by the dispatcher thread.
Looks like flush has some problem
"Dispatcher-Thread-1" daemon prio=5 tid=0x5cdb88 nid=0xf runnable

This thread gets blocked and subsequent threads are blocking on callAppenders. One
thread is trying to get a lock on append(),
"Initial Poll DispatcherWorker#7" prio=5 tid=0x3377b0 nid=0x39 waiting on monitor

at org.apache.log4j.Category.forcedLog(Category.java:372)
at org.apache.log4j.Category.log(Category.java:846)
But since buffer is full, it waits there (AsyncAppender.java line # 85).
Could you please suggest me a workaround or solution.
