A few days ago a friend asked me how to resolve this question if hit it from QQ. at that time I'm on vacation , sort out today.
This case with DB version 9.2.0.4, OS version He did not tell me.
[oracle@anbob ~]$ oerr ora 27143
27143, 0000, "OS system call failure"
// *Cause: OS system call failed
// *Action: check errno and contact Oracle support
Explanation:
============
This problem is occurring because you are running out of resources on your machine that are required for the servers to startup.
The error messages:
skgpspawn failed:category = 27143, depinfo = 24, op = pipe, loc = skgpspawn2

puts forward some ideas and methods for to solve this problem

1,Check free memory and swap on the server. 
2,Check the oracle account's process limits? 
$ ulimit -a
3,Is the executable large memory enabled?
4,alert log file ,listener.log size too big?
