Error description
Segments created by the checkpoint/restart support framework of the filesystems is not deleted even after the process that was checkpointed exits. This is difficult to detect as there is no visible symptom such as crash or hang. The memory leaked by these segments is usually small (a couple of real page-frames). Therefore this may be visible as a memory leak only if a very large number of processes were checkpointed and then exited as zombies before being restarted.

Problem summary
Segments created by the checkpoint/restart support framework of the filesystems is not deleted even after the process that was checkpointed exits. This is difficult to detect as there is no visible symptom such as crash or hang. The memory leaked by these segments is usually small (a couple of real page-frames). Therefore this may be visible as a memory leak only if a very large number of processes were checkpointed and then exited as zombies before being restarted.
Problem conclusion
Process exit path now deletes the checkpoint/restart segments for the filesystems when a process transitions to the zombie state. Affect bos.mp64.
