semget: No space left on device DA 启动不了apache
This relates to semaphores on your system (you’ve run out). Run the following to clear them out:
ipcs | grep apache | awk ‘{print $2}’ > sem.txt
for i in `cat sem.txt`; do { ipcrm -s $i; }; done;
If this becomes a common occurance, then you may need to change your ipcs semaphore limits.
Set the following in your /etc/sysctl.conf:
kernel.msgmni = 1024
kernel.sem = 250 256000 32 1024
and reboot your system to load in those values.
