We have a build slave set up under zOS Unix System Service.
During the build, we execute a shell script mounted via NFS mount from a server.
From time to time, the execution of such shell script throws an exception

Note: the error does not ALWAYS occur, the build runs fine most of the time, but occurs only occasionally. However when it occurs, the build will ABEND and no workaround is found. So I am opening it as Priority "Major".

The following is what's defined in Execute Shell Command in the Build tab in configuration for the project:
#!/bin/sh
sh -x <a_prebuild_shell_script_located_on_nfs_server>

The following is the error from the console output:
....
[EnvInject] - Injecting environment variables from a build step.
[EnvInject] - Injecting as environment variables the properties content
_BPXK_AUTOCVT=ON

[EnvInject] - Variables injected successfully.
ERROR: Build step failed with exception
