Can't find shared memory for database cache. [No such file or directory]

[jcesario]

Zabbix 1.6.8

I have seen a lot of posts about this but no solution. Can anyone explain why this happening?

This is where i happens in dbxcache.c


shm_id = shmget(shm_key, sz, 0);

if (-1 == shm_id)
{
zabbix_log(LOG_LEVEL_ERR, "Can't find shared memory for database cache. [%s]",strerror(errno));
exit(1);
}
