Known Issues chapter:

 

Resource Temporarily Unavailable Errors on AIX

Valid on AIX

When running jobs on AIX, some of the jobs fail to complete with submission errors (SUBERROR). The job log contains the following error message:

 

CAWA_E_20039 Cannot fork a new process to execute the job:/usr/bin/ksh, reason:Resource temporarily unavailable.Error code: 11

Solution:

 

The error can occur because of a memory issue.

 

Check the maximum number of user processes on your system using the following command:

 

lsattr -E -l sys0 -a maxuproc

Sample output:

 

maxuproc 128 Maximum number of PROCESSES allowed per user True

To resolve the issue, we recommend that you increase the number of user processes to 1024 using the following command:

 

chdev -l sys0 -a maxuproc=1024
