dfsort error

[prasadraobn]

I'm new to this JZOS. I'm getting the below error code and I'm not getting why?

JVMJZTK1039E Child shell process received signal: 9
com.ibm.jzos.RcException: child process received signal RC=-2 (0xfffffffe)
at com.ibm.jzos.Spawn.waitPid(Native Method)
at com.ibm.jzos.Spawn.waitChild(Spawn.java:69)
at com.ibm.jzos.DfSort.getReturnCode(DfSort.java:340)
at casmvs.jsort.main(jsort.java:182)

1. Is it because of memory issue or time? What can be done to resolve this?
2. What are the different rcexceptions? any documentation link

JVMJZTK1039E Child shell process received signal: 9
-- this has to do with your STDENV shell script exiting with a signal.
perhaps add "set -x" to the beginning to see what is going on

com.ibm.jzos.RcException: child process received signal RC=-2 (0xfffffffe)
at com.ibm.jzos.Spawn.waitPid(Native Method)

at casmvs.jsort.main(jsort.java:182)
-- this is a signal to the child DfSort process

Its difficult to tell what is going on without seeing your job input and full job log.
