Run the IPCS command to list Interprocess Communication (IPC) status as follows.

Now find the process of destroyed process using their shmid as follows.

oracle_24 247335 oracle DEL REG 0,15 399835141 /SYSV00000000
[root@node1 ~]# 

Now kill these process :
[root@node1 ~]# kill -9 194509 247335
[root@node1 ~]# [root@node1 ~]# [root@node1 ~]# lsof | grep 399835141
