这次提示：
zabbix_agentd [12234]: Can not create Semaphore [No space left on device]
zabbix_agentd [12234]: Unable to create mutex for log file
这次又是另外一个错误，根据上次的经验，通过修改sysctl.conf试试
kern.ipc.shmall=40960000 kern.ipc.shmmax=204800000
居然好用了
日志提示：Can’t allocate shared memory of size 8388608 [Cannot allocate memory]
解决办法：
eventually I have successfully get around the problem by modifying the below two setting as below:-
kern.ipc.shmall=40960000
kern.ipc.shmmax=204800000
I believe it would be too large but I really don’t have an idea on how large should I modify the setting before I can get it run, so a bit overkilling. Grateful if anyone got an idea on a better setting.
