IBM Platform Symphony 7.1 Interim Fix #436027 Readme File

Abstract

Interim fix for Linux 64-bit hosts to prevent VEMKD and EGOSC from crashing under race conditions on a file system.

Description

When the EGO_ENABLE_FSYNC parameter is not configured, the EGO status files might be incomplete on an unstable file system, causing the VEMKD and EGOSC to crash.

This fix applies only to Linux 64-bit hosts.
