Hi

Here is leak from our system, not sure if this is the same issue. Application is molpro which is causing this leak. (pristine lustre 1.8.2)

             total       used       free     shared    buffers     cached
Mem:      32962040   32869120      92920          0        632    4201332
-/+ buffers/cache:   28667156    4294884
Swap:      1020116    1020116          0
