Error description

Loadleveler jobs are failing intermittantly with error
0031-24 no response.  rc = 1
The jobs had mutilple poe invocations and it was found
the when the Loadleveler Starterlog rolled over
to a .old and new Starterlog was created the failure
could occur.
An example failure we saw in the Starterlog was:
 Error within this file: 12/10 09:19:58 TI-0
d1n7s.2540272.0
 LoadL_starter: 2512-902 Unable to set process limits for
user.
 LoadL_starter: 2539-752 The getgroups system call failed
for user
 climprod. errno=1 [Operation not permitted.]

It appears that when the StarterLog is rolled over to the
*.old file the effective user id is changed to root
without changing the real id. This seems to be why the
starter child process cannot switch to root.
As a work around, the customer could try increasing
the size of the StarterLog to reduce the frequency
of this failure.
APAR IZ48539 was created for the problem:
The <jobid>.machinefile may not be deleted in the
execute directory. The LoadL_starter can switch
between root, the loadl id and the userid while it
is running. The customer saw that the machinefile
was owned by the id "loadl" by the debug code we used
to remove it.  Both issues are fixed by APAR IZ50255.
IZ48539 is being closed as a DUP of IZ505255

Local fix

Problem summary

A job which invokes POE several times will eventually fail
with the following starter error:
LoadL_starter: 2512-902 Unable to set process limits for
user.
LoadL_starter: 2539-752 The getgroups system call failed for
user

Problem conclusion

Code was added to insure that the child starter process is
started as root so that the process could set up the
environment and credentials to run the job.

Temporary fix
