tail: inotify cannot be used, reverting to polling: Too many open files

tail -f catalina.out 出现警告:

 tail: inotify cannot be used, reverting to polling: Too many open files

lsof | awk '{ print $2; }' | sort -rn | uniq -c | sort -rn | head

查到是tomcat进程打开了很多文件,处理方法:

在 /etc/sysctl.conf文件中加入下面的配置:

fs.inotify.max_user_watches=1048576
fs.inotify.max_user_instances=1048576

 

sysctl -p /etc/sysctl.conf 使修改生效。再次执行 tail -f catalina.out 就可以了。
