CVSROOT: /cvs/cluster
Module name: cluster
Branch: RHEL4U4
Changes by: bmarzins at sourceware.org 2006-09-14 20:28:30
Modified files:
gulm : Makefile
gulm/src : core_main.c gulm_defines.h lock_main.c
ltpx_main.c main_main.c
Added files:
gulm/src : log.c log.h
Log message:
This fixes bz 206160 (the RHEL4 version of the INRA bug). Gulm now is locked
into memory and has a seperate thread responsible for writing to syslog. This
keeps it from blocking while under memory pressure, so heartbeats can still get
out.
