All the exception is throw when call "AbstractWorkGang::add_workers", and
in add_workers, if the new worker not created, will exit with this exception
(
https://hg.openjdk.java.net/jdk9/jdk9/hotspot/file/b756e7a2ec33/src/share/vm/gc/shared/workerManager.hpp#l70
)
for (uint worker_id = start; worker_id < end; worker_id += 1) {
WorkerThread* new_worker = NULL;
if (initializing || !InjectGCWorkerCreationFailure) {
new_worker = holder->install_worker(worker_id);
}
if (new_worker == NULL || !os::create_thread(new_worker, worker_type)) {
log_trace(gc, task)("WorkerManager::add_workers() : "
"creation failed due to failed allocation of native
%s",
new_worker == NULL ? "memory" : "thread");
if (new_worker != NULL) {
delete new_worker;
}
if (initializing) {
vm_exit_out_of_memory(0, OOM_MALLOC_ERROR, "Cannot create worker GC
thread. Out of system resources.");
}
break;
}
created_workers++;
os::start_thread(new_worker);
}
So I think there are 2 possibilities:
exceed process number limit, so new thead ceation failed
memory not enough, so creation failed
Because in all the hs_err file, we can see the memory is
enough(MemAvailable: 521512832 kB), so the most possible is exceeding
process number limt.
