Hi All...
With the last WMS update
[root@wms01 etc]# rpm -qa | grep glite-WMS
glite-WMS-3.1.20-0
the glite-wms-workloag is using (again!) 1.3G of memory, and the machine
is heavily swapping.
3320 glite 20 0 175 3391:37 63.5 2705m 1.3g 4608 S
glite-wms-workl
This was a known problem seen in the past which was solved by using
google_perf_tools. The problem now is that
/opt/glite/etc/init.d/glite-wms-wm does not has the
"use_google_perf_tools=1" option anymore.
Does someone knows the workaround to this issue?
Cheers
Goncalo
