LSB_MAILSIZE_LIMIT

Description

Limits the size in KB of the email containing job output information.

The system sends job information such as CPU, process and memory usage, job output, and errors in email to the submitting user account. Some batch jobs can create large amounts of output. To prevent large job output files from interfering with your mail system, use LSB_MAILSIZE_LIMIT to set the maximum size in KB of the email containing the job information. Specify a positive integer.

If the size of the job output email exceeds LSB_MAILSIZE_LIMIT, the output is saved to a file under JOB_SPOOL_DIR or to the default job output directory if JOB_SPOOL_DIR is not defined. The email informs users of where the job output is located.

If the -o option of bsub is used, the size of the job output is not checked against LSB_MAILSIZE_LIMIT.

If you use a custom mail program specified by the LSB_MAILPROG parameter that can use the LSB_MAILSIZE environment variable, it is not necessary to configure LSB_MAILSIZE_LIMIT.

Default

By default, LSB_MAILSIZE_LIMIT is not enabled. No limit is set on size of batch job output email.
