environment limitations

["Urbanek, Marty" <Marty_Urbanek@xxxxxxxxxxxx>]

Not sure this belongs here, but it's sort of qshell, environment, java ...

I need to know the OS/400 limits on environment variables. Is there a
maximum number of variables, length of a single variable, and/or total size
of all environment variables? I seem to be running into some limitations.

I am on V5R2.

Simplified story:  We have a shell script that calls another shell script
that calls some java programs. Both shell scripts set environment variables,
at least one of which is very large, over 4KB. The environment has grown as
the related software has grown. Now the java program has started failing
with an error 

./my.sh: 001-0078 Process ended by signal 5. 

which I see on the qsh terminal screen (or in a QPRINT file if I run qsh in
batch).

I have discovered via testing that if I do not set the large environment
variable, the error does not occur. Unfortunately, the large variable is a
java classpath and it is necessary for other parts of the product to work.

Many of these environment variables are also exported. Perhaps there is some
limitation on that as well?

Anybody know about these limits and if/how I can control them?

THANK YOU,
