>Description:
When you do a ipcs -opq, it show message queue numbers that are negitive:
Message Queues:
T     ID     KEY        MODE       OWNER    GROUP CBYTES  QNUM LSPID LRPID
q  65536        100 --rwarwarwa      mdh programmer    576     12  53768  53738
q 720897         10 --rwarwarwa      mdh programmer      0      0  96326    560
q 131074          0 --rw-rw-rw-      mdh programmer      0      0    560    565
q 131075          0 --rw-rw-rw-      mdh programmer      0      0    560    568
q -1419182076          0 --rw-rw-rw-      mdh programmer      0      0  46751  46772
q -1627324411          0 --rw-rw-rw-      amh programmer     48      1  79239      0
q -1015611386          0 --rw-rw-rw-      amh programmer     48      1  79239      0
q 2071789575          0 --rw-rw-rw-      mdh programmer      0      0  53738  53768

Because of the queue number, you can't use ipcrm to clear them out.  It would
be nice if the queue numbers would not get bigger then a 5 digit number.

>How-To-Repeat:
Use a program that creates and deletes a message queue every 5 minutes.
