IBM Spectrum LSF 10.1 Fix 489245 Readme File

Abstract

P101909. When the LSF daemon wrapper is enabled, new jobs might not run on execution hosts that are running for a long time.

Description

Readme documentation for IBM Spectrum LSF 10.1 Fix 489245 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

When the LSF daemon wrapper is enabled (that is, if "LSF_DAEMON_WRAP=y" is defined in the lsf.conf file), new jobs might not run on hosts that are running for a long time.
If this occurs, the message "Too many open files" is recorded in the sbatchd log, and the file descriptor leak can be detected by running the lsof command for sbatchd daemons.
