Figure out where Zabbix is trying to create this semaphores. ls -l the that location to see it's permissions. One of two things may be the cause, 1) if Zabbix is creating as it's own user and that user does not have permission to function in the location then it needs permission (which could be done one of several ways), 2) If Zabbix is creating the semaphores as your user then the same as 1 just give yourself permission to function at the location. A quick, albeit unsecure, test is to: chmod 777 [semaphore_directory] If this works, then you have your answer and can return the dir to it's original state and implement a more secure method of permissions. This is just an educated guess, so hope it helps. <pre class="moz-signature" cols="72">-- Fred <a class="moz-txt-link-abbreviated" href="http://www.fwrgallery.com">www.fwrgallery.com</a> "Life is like linux, simple.
