shmget: [EEXIST][17]: key XXXXXXXX: shared memory already exists ERROR

I can not bring up engine due to the following message: shmget: [EEXIST][17]: key XXXXXXXX: shared memory already exists mt_shm_init: can't create resident segment I ran "ipcs -m" and found the shared memory segment ID and key and cleaned it with "ipcrm -m <shmkeyid>" but the error persists and IDS engine is not starting up. Tried changing SERVERNUM but error persists. It is strange since I did not reboot the server nor did not change any onconfig parameter.
