Bad UDP packets send by Zend Server Windows Services?

by **beeare** on Wed Jul 18, 2012 2:20 pm

Hello,

one of our customers is using Zend Server Community Edition (PHP 5.2) and complains about bad UDP packets sent by broadcast et each reboot of the server on which the Zend Server Windows Services (Zend Deployment, Zend Java Bridge, Zend Job Queue, Zend Monitor, Zend Session Clustering) are running. The customer makes one or more of the Zend Server services responsible for this misbehavior. We could deactivate all Zend Server services except the Java Bridge (because we need this service) to avoid this kind of problem, but perhaps you can provide a hint what's going wrong there.

Best regards,
Benjamin

Can you post the exact error message they are reporting and where they are seeing this?

I've asked the customer for the error details. As soon as I've received them, I will post the details.

BTW it may not actually be an "issue" per se. About the only thing I know that uses UDP broadcast is our session clustering mechanisms and since that is "off" for Server CE it's probably benign but let's see what we get from your customer.

Hi,

We get these kinds of messages on many servers which are on the same VLAN as the zend servers :
/var/adm/messages.3:Jul 22 02:03:16 arone ip: [ID 390400 kern.notice] dst FFFFFFFF src 7F000001
/var/adm/messages.3:Jul 22 02:13:16 arone ip: [ID 390400 kern.notice] dst FFFFFFFF src 7F000001

It seems to happen everytime the engine is restarted.

Rgds,
