Having a strange problem. We were adding a network switch. We started using the Wizard to add the switch, and it would hum along in the verification for a good 2min then come back saying it failed. No real reason given. So we decided to use the Wizard to add things in batches, figuring we were just running into a timeout on the scripts(s). Things work fine up until around the 600 mark on number of services for that host (being a switch). Then the verification fails and the host does not even show up. Delete those just added, and the host comes back, and all seems to be fine.

Thanks
Mitch

Please run the following and post the results:

Code: Select all

grep "memory_limit" /etc/php.ini
grep "max_execution_time" /etc/php.ini
grep "max_input_time" /etc/php.ini

Posted: **Fri Mar 20, 2015 11:16 am**

Code: Select all

# grep "memory_limit" /etc/php.ini
memory_limit = 128M
# grep "max_execution_time" /etc/php.ini
max_execution_time = 30     
# grep "max_input_time" /etc/php.ini
; max_input_time
max_input_time = 60

More info on the device:

That switch is a Cisco Nexus 5596 with 5 FEX’s attached. Each FEX has 48 copper ports and 4 10GB uplinks back to the 5596. So a very large number of ports.

Thanks

Try increasing all of these values (memory_limit, max_execution_time, and max_input_time). Also, add the following line on the bottom of the "/etc/php.ini" file:
