Description tcp 2011-03-21 06:12:29 EDT
The gNFS server leaks memory under I/O. Particularly, the file operation sequence - (Open, Read, Close) of a large number of files results in the memory footprint of the gNFS process to grow quickly. The memory usage does not reduce even after successfully unmounting all the clients.

Find attached the following:

* valgrind report on Linux (courtesy Shishir)
* libumem report from Solaris

Attaching the valgrind log for gNFS, i did file operation sequence (Open, Read, Close) of a large number of files (1000 files each of size 2k). Not seeing any memory leak.
