du: fts_read 失败: 无法分配内存

今天在查看一个大的文件时突然报出一个du: fts_read 失败: 无法分配内存的错误。

用

ulimit -a

查看下

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 63795
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
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) 63795
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

　　原来stack size              (kbytes, -s) 10240  //只有10M

修改下大小

 [root@180caldomain ~]# ulimit -s
 [root@180caldomain ~]# ulimit -a
 core file size          (blocks, -c)

OK
