Resolution
If the xcomd deamon is not running and you have uninstalled the previous release, then you want to issue the following commands:
ipcs -m --> this command will show you the shared memory segments. If XCOM has a segment you will see:
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000019 131072 root 666 338251 1
ipcs -s ---> this command will show you the semaphonres. If there is a semaphore for XCOM then you will see this:
------ Semaphore Arrays --------
key semid owner perms nsems
0x00000000 0 root 600 1
0x00000000 65537 root 600 1
0x00000019 262146 root 666 1
"0x00000019" is XCOM's key. If you see the above then you need to get those cleared out. Please check with your Linux administrator.
