Apache does not start. Error shows Cannot create SSLMutex

SSLMutex - Semaphore for Internal Mutual Exclusion of Operations - used for handling SSL semaphore connections

Error log shows

[Mon xxx xx xx:xx:xx xxxx] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)
[Mon xxx xx xx:xx:xx xxxx] [error] (28)No space left on device: Cannot create SSLMutex

Problem is there are semaphore-arrays left owned by my apache

ipcs -s | grep apache

Removing these semaphores by

ipcs -s | grep apache | perl -e 'while (<STDIN>) { @a=split(/\s+/); print `ipcrm sem $a[1]`}'
