我想这是由每用户限制造成的,但与其他用户比较时没有什么不同.
这是针对adtech的ulimit -n：
[adtech@hmaster87 root]$ulimit -a core file size (blocks,-c) 0 data seg size (kbytes,-d) unlimited scheduling priority (-e) 0 file size (blocks,-f) unlimited pending signals (-i) 192025 max locked memory (kbytes,-l) 64 max memory size (kbytes,-m) unlimited open files (-n) 655360 pipe size (512 bytes,-p) 8 POSIX message queues (bytes,-q) 819200 real-time priority (-r) 0 stack size (kbytes,-s) 10240 cpu time (seconds,-t) unlimited max user processes (-u) 1024 virtual memory (kbytes,-v) unlimited file locks (-x) unlimited
这个用于量子：
[quanta@hmaster87 ~]$ulimit -a core file size (blocks,-v) unlimited file locks (-x) unlimited
adtech运行的进程数：
[root@hmaster87 ~]# ps -U adtech | wc -l 25
还有其他要检查的东西吗？

正如我在下面的评论中所说,我的同事发现了可能是罪魁祸首的过程：

通过杀死这个过程,问题就会消失,但我们仍然不知道超出了哪个限制.

@ favadi的回答是正确的,但我在这里更新以防有人google这个帖子.
