[Lustre-discuss] Lustre Client - Memory Issue

[Jagga Soorma]

Hi Johann,

I am actually using 1.8.1 and not 1.8.2:

# rpm -qa | grep -i lustre
lustre-client-1.8.1.1-2.6.27.29_0.1_lustre.1.8.1.1_default
lustre-client-modules-1.8.1.1-2.6.27.29_0.1_lustre.1.8.1.1_default

My kernel version on the SLES 11 clients is:
# uname -r
2.6.27.29-0.1-default

My kernel version on the RHEL 5.3 mds/oss servers is:
# uname -r
2.6.18-128.7.1.el5_lustre.1.8.1.1

Please let me know if you need any further information.  I am still trying
to get the user to help me run his app so that I can run the leak finder
script to capture more information.

Regards,
-Simran
