So all the targets (50+) in Unknown state. In the java lang outofmemoryerror unable to create new native thread eclipse grid its in Blocked agent. We tried to unblock and did the Agent Resynchronization for this. At the java.lang.outofmemoryerror: unable to create new native thread linux end getting below error message as Thread-9668 ERROR ThreadPool: Could not create thread, ERROR=12:Not enough space In the emagent.log seeing below error 2010-11-12 21:03:48,950 Thread-9966

At one site (and only one site - our product is widely deployed to many environments), we randomly get the following error: java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Unknown Source) Operating system is Windows unable to create 7 64 bit We are running in a 32 bit JVM ( 1.7.0_45) Using Windows Task Manager, I can see that the process has 39 native threads (not very many), so we don't have a thread leak in our app... There are no other processes consuming lots of threads (Explorer has 35, jvisualvm has 24, iexplore has 20, ... I don't have an exact count, but we are probably looking at maybe 300 threads for the user total). I have attempted to attach JVisualVM, but it fails to connect to the process (probably b/c of thread exhaustion). But from the metrics I can obtain from JVisualVM, the number of Java threads is about 22 live and 11 daemon. The heap is well behaved - heap is 500MB with 250MB actually used. The process is launched with -Xmx512m Our process is showing Memory usage (in Task Manager) of 597,744K. The workstation has 8GB RAM, of which only 3.8-4.0GB are used (I know, a 32 bit process won't access all of that, but there's still plenty) Used VMMap, and the stack is 49,920KB size with 2,284K committed. The process shows 5358KB free, and the largest allocatable block in the free list is 1,024K in size. I used Resource Monitor and it's showing the Commit (KB) to be 6304
