Hi,

SYSTEMS AFFECTED:
lcgrb01.gridpp.rl.ac.uk - RAL - LCG -RB

ACTION(S)
Due to deadlock in
http://marianne.in2p3.fr/datagrid/bugzilla/show_bug.cgi?id=2054

the following was done.

---------------------------
/etc/init.d/edg-wl-jc stop
/etc/init.d/edg-wl-lm stop
/etc/init.d/edg-wl-wm stop
/etc/init.d/edg-wl-ns stop
rm  /tmp/workload_manager/input.fl
(Not exactly sure what the consequences of this are but it does
 the job.)
/etc/init.d/edg-wl-jc start
/etc/init.d/edg-wl-lm start
/etc/init.d/edg-wl-wm start
sleep 60
/etc/init.d/edg-wl-ns start
---------------------------

WP1 has already fixed this for real and will appear with
LCG2 RB.

PROBLEMS RESOLVED
RAL RB operational again.
