Resolution
如果出现错误“资源暂时不可用”,则表示作系统资源不足。
在这种情况下,请在服务器重新启动之前检查 SAR 报告。
00:00:01 runq-sz plist-sz ldavg-1 ldavg-5 ldavg-15 blocked
16:40:01 20 32595 9.01 9.97 5.46 0
16:50:01 15 32611 1.49 2.81 3.70 0
有 32,611 个进程正在运行。但是,允许的最大进程数为:kernel.pid_max = 32768 (从日志文件中获取此信息 env.txt 或从作系统命令”sysctl -a | grep pid_max“
因此,这得出的结论是,服务器达到了允许的最大进程数。客户可以使用命令“进行检查”ps aux“来审查是否需要所有进程,或者可能是进程未正确停止,并继续创建新进程。
修复了不必要的进程解决了问题
