EVALUATION This bug is only possible on a multiprocessor machine with a heavy load of threads and a constant lack of memory. GC thread is trying to suspend all Java threads to do Garbage Collection and fails to suspend one of them. ###@###.### 2002-01-24

SUGGESTED FIX According to MSDN: "If the thread is making a kernel call, SuspendThread fails. An application may need to repeat the SuspendThread several times for it to succeed." The fix would be to call SuspendThread() inside the loop for a reasonable number of times. See http://jpsesvr.sfbay.sun.com:8080/ctetools/servlet/sun.cte.codeMngt.ViewDetail?op=approve&id=43 for details. ###@###.### 2002-01-24
