Can't Get Accurate Error Messages When Ptyprocess.exec Failed

[eddiezhou1]

I hope to get accurate error messages instead of Unknown reason, when I execute some non-existent commands.

java.io.IOException: Exec_tty error:Unknown reason
	at com.pty4j.unix.UnixPtyProcess.execInPty(UnixPtyProcess.java:219) ~[pty4j-0.11.4.jar!/:na]

Reason: Not enough storage

Solution ：

1. Increase memory capacity
2. Modify memory strategy （vm.overcommit_memory =1)
3. Check for memory leaks
