[core:emerg] [pid 7732:tid 140396300543936] (28)No space left on device: AH00023: Couldn’t create the proxy mutex
[proxy:crit] [pid 7732:tid 140396300543936] (28)No space left on device: AH02478: failed to create proxy mutex

Fix:

ipcs | grep apache | awk ‘{print $2}’ > sem.txt
for i in `cat sem.txt`; do { ipcrm -s $i; }; done

Permanant fix:

vi /etc/sysctl.conf

kernel.msgmni = 1024
kernel.sem = 250 256000 32 1024
