Description Casey Dahlin 2010-06-07 14:14:27 EDT
If a file or directory in /proc is kept open after a task has exited, its inode retains a reference to the task struct, thus preventing a large chunk of memory from being freed. Under the right workload, staggering amounts of ram can be eaten by dead task structs that are being pinned by /proc inodes.
