I don't know anything about unix, but it looks like your client assignments are long instead of int32.

16-bit 0xFFFF
32-bit 0xFFFFFFFF
48-bit 0xFFFFFFFFFFFF
64-bit 0xFFFFFFFFFFFFFFFF

this = 0x7fc5dc0c86f0 (assuming this is the client id. If it's a memory pointer, then I don't know...)

EDIT: That would be over 127 terabytes of memory though..if it were a pointer...
