The procedure has changed on how to find the Memory Segment or Semaphore taken by Cop in versions 2.1.3.10 and later. Cop randomly uses semaphores; it is no longer the 0x834 key.
1. At a Unix prompt type:
> ipcs -a
2. Go to the $SP_SYS_VARDIR/rim directory. There will be two files located there: shmaddr.loc and shstinfo.ipc
3. Type the following:
> od -x shmaddr.loc
> od -x shstinfo.ipc
The output will be a display of groupings of letters or numbers. The 6th and 7th grouping will be the Key to compare to the output of the ipcs -a command.
For example:
> od -x shmaddr.loc
0000000 0000 00d2 fd40 0000 4400 bebb 0080 0000
> od -x shstinfo.ipc
0000000 0000 0261 fe90 0000 4100 bebb 0010 0000
From this example the 4400 bebb and the 4100 bebb would represent the third column KEY of the ipcs -a output. Once located the Shared Memory or Semaphore can be removed by the ipcrm command.
