Unable to retrieve message error in the PureMessage Quarantine preview

Hi everyone,

Wondering if anyone else has run into the problem where they can view the metadata for messages on the CSM, but when clicking the envelope gets the "Unable to retrieve" error message.

Full error:

 > Unable to retrieve message for preview. Please ensure that the Manager service is running on your mail filtering

 > server(s) and check the PureMessage log for more information about the actual cause of the error.

I checked the pmx_log in /opt/pmx/var/log, and I see the following:

4 2010-01-28T17:01:28 [23376,quarantine] Request servername/.../pmx-qmeta-index.cgi;insert_body=1&insert_hits= failed: Unable to instantiate local message object for global id 2421273-5 Content-type: text/plain failure

4 2010-01-28T17:01:34 [23385,quarantine] Request servername/.../pmx-qmeta-index.cgi;insert_body=1&insert_hits= failed: Unable to instantiate local message object for global id 2421273-5 Content-type: text/plain failure

Firewall ports between the servers are open as far as I can tell, but don't know of the full list of ports that should be checked.  That would be helpful as well if anyone has it.

Any ideas?  We're on PMX version 5.5.9 build 388399, database version 5.402.

Thanks,

Matt.
