You may want to look at this, I get a Null pointer exception in PersistentServer
Example (Please look at stack trace from Debbie's mail). I have attached the tar
file, To run this example

1. Untar it
2. gnumake build
3. gnumake runorbd
4. gnumake register
5. gnumake runc

PersistentClient calls a method on Persistent Server every three seconds and
kills it. Wait for multiple iterations, it will fail after 'n' number of calls.
I have seen the failure sometimes after 3 calls and sometimes after 7 calls.
