这个你只能自己调下 core 层 poller wait 的实现了，看下为啥会失败。。通常是编译问题，先确认是否用上了 epoll，然后再看下为啥 epoll 失败。。

You can only adjust the core layer poller wait implementation yourself to see why it fails. . It is usually a compilation problem. First confirm whether epoll is used, and then look at why epoll fails. .

是系统 ulimit 的打开文件数特别大造成的，改成 65535 没问题了 core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 59388 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1073741816 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited

It is caused by the extremely large number of open files in the system ulimit. Changing it to 65535 will solve the problem. core file size (blocks, -c) unlimited data segment size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 59388 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1073741816 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
