Hi,
Does anyone have any clues where I might start looking for the reason
behind commands within the procps package just hanging?
The built-in busybox commands work fine. I wanted vmstat from procps,
but it hangs too.
Strace shows:
execve("/bin/ps", ["ps", "aux"], [/* 15 vars */]) = 0 <0.001063>
brk(0) = 0x10040000 <0.000065>
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x4801e000 <0.000084>
access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or
directory) <0.000104>
