Alguém tem noção do que pode ser isso?

Att.

try to restart your mysql... that worked for me... if it doesn't work for you maybe you need more space on disc or cache.

That work for me.. hope it works for you.

Hy Osorio.

Thanks, Can it really be HD? mine is 40 GB.

[root@omega ~]# df
Sist. Arq. 1K-blocos Usad Dispon. Uso% Montado em
/dev/hda1 37853184 2310948 33588332 7% /

Do you think better to change the Hard Disk?

Also restarted the MySQL Server but the message remains Zabbix server is unreachable.

When it happens to me it was also because the cache size. I think you should check if you can access to your phpmyadmin or where is your database. In my case when i try to access to phpmyadmin there was a notice about no space left. So i search for a script to repair mysql and then i restart the server. Check the files size... maybe a tmp folder is too big. Make sure to serch here on the forum "Zabbix unreachable" and check other users posts because sometimes are different problems related to this message.

Hope you find a solution! ;)

Update:
Now i remember that mine was beacuase i had too many notification emails.

Update #2:
Ironicly today it happen to me... now is solved. Put this on Putty:

mysqlcheck -u user -p nameofdb --auto-repair

Put your mysql username in user and the name of the data base on nameofdb. Thats what i did and now is working again.

Resolvi este problema, comprei outra HD de 320 Sata. Refiz a reinistalação do centOS e recompilei novamente a instalação do Zabbix, normalizado
