我正在使用Linux 12 SP2。当线程超过420时,始终无法创建线程。
错误日志:
Exception in thread "main" java.lang.OutOfMemoryError: unable to create new native thread (424 threads running, rlimit: STACK 8192k, CORE 0k, NPROC 30654, NOFILE 16394, AS infinity, DATA infinity, CPU infinity, FSIZE infinity, MEMLOCK 64k , Memory: 4k page, physical 528062120k(345461208k free), swap 2097148k(2097148k free) )
从日志中,您可以看到服务器容量足以创建更多线程。实际上有很多线程在OS下运行。你对这个问题有什么看法吗? 见下面的详细信息:
