4.解决方案

1.vi /etc/systemd/system.conf

Set DefaultTasksMax to 'infinity'

2.Restart OS

5.问题原因

  在Linux 7或Suse 12上,使用了systemd新的启动方式,这个在Linux 6和SUSE 11上是没有的,当这个启动之后,就会忽略掉/etc/security/limits.conf下的设置。

  而该文件的一个参数，DefaultTasksMax设置为默认值（512），限制了可在节点上创建的最大任务数。此设置还影响OS上的maxpid值。

6. SUSE 12sp3修改方法及参数检查

#################添加limits参数###################
