IBM Platform LSF 9.1.1 Fix 399861 Readme File

Abstract

P101675. Fix to prevent the master elim from incorrectly reporting the error message "readLoadUpdateFromSubElim: Protocol error: loadCnt cannot be read from elim".

Description

Readme documentation for IBM Platform LSF 9.1.1 Fix 399861 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

When the lim daemon starts up, the master elim may report the following error message in the log file:

readLoadUpdateFromSubElim: Protocol error: loadCnt cannot be read from elim

This error message is a false alarm. The root cause is that some elims may start, but quickly exit with ELIM_ABORT_VALUE. A race condition might happen where the master elim read the exited child elim process before receiving the SIGCHLD signal of the child, in which case the read fails and the master elim displays this error message.
