IBM Spectrum LSF 10.1 Fix 600731 Readme File
Abstract
P104388. This fix prevents the mbatchd daemon from hanging when it terminates jobs on a reclaimed host in LSF resource connector.
Description
Readme documentation for IBM® Spectrum LSF 10.1 Fix 600731 including installation-related instructions, prerequisites and co-requisites, and list of fixes.
This fix addresses the following issues:
In LSF resource connector, when a host is reclaimed, the mbatchd daemon requeues or terminates jobs on that host. When mbatchd terminates jobs, it might run into a dead loop, causing the mbatchd to use 100% CPU, so mbatchd hangs and is not responsive.
