unable to create new native thread

不是 Java heap space 相关报错
检查当前进程数:
top -H
系统进程相关参数:
ulimit -a
每个用户都是独立,通过切换用户进行查看
启动容器报错:
starting container process caused "read init-p: connection reset by peer"
怀疑跟 pids.max 值低了有关
https://github.com/opencontainers/runc/issues/1914
查看当前值:
cat /sys/fs/cgroup/pids/kubepods/pids.current
查看配置的最大值:
cat /sys/fs/cgroup/pids/kubepods/pids.max
调整系统该配置值,
echo 327680 > /sys/fs/cgroup/pids/kubepods/pids.max
服务器配置越高,这个值可以配置越高
由于/sys/是临时文件系统,重启后会丢失,所以放在定时任务中修改:
echo ‘0 * * * * echo 327680 > /sys/fs/cgroup/pids/kubepods/pids.max‘ >> /var/spool/cron/root
