I was not able to find any other instance of the program on the process table.

Solution

1. Try to remove the lock file


[root@blackbox bbaby]# rm -f /opt/compaq/cpqacuxe/bld/locks/CPQACU_MUTEX
[root@blackbox bbaby]#


In my case this was not resolving problem. I was getting the same error message even after removing lock.

2. Do an strace and find what is blocking

[root@blackbox bbaby]# strace -f /opt/compaq/hpacucli/bld/hpacucli

In this case need to delete the semaphore *7798791*

3. Delete the blocking semaphore

{terminal}
[root@blackbox bbaby]# /usr/bin/ipcrm -s 7798791
[root@blackbox bbaby]#
{terminal}

4. Verify whether it still exits or not

[root@blackbox bbaby]# /usr/bin/ipcs -a
