Centos 7 - Zabbix 3.4.7 - cannot create Semaphore: [28] No space left on device

[hernan]

Hi Team,

I received the following error message on the zabbix_server.log:


*****************************************
cannot create Semaphore: [28] No space left on device

**********************************
The firewalld is disabled and the ipcs -ls output is the following:

***********************************
max number of arrays = 128
max smaphores per array =250
max semaphores system wide = 32000
max ops per semop call = 32
semaphore max value = 32767
************************************

Can you help me with this problem?

Thanks in advance.

Regards.

I guess it has failed many times and has created a lot of semaphores?
Please check the semaphore that has been created with the following command.

# ipcs -s

If you have not started the process for Zabbix, the semaphore whose owner is zabbix is unnecessary.
Please remove unnecessary semaphores with the ipcrm command and then start up.
