 Hi,
 
 My connection to Postgres keeps failing every couple of hours. I did

 2.0b6 at the moment.
 
 Does anyone have a version number that I can try that will re-establish
 a connection on failure.

Michael,

if you look at the DA (db.py) source you will see that it actually tries to 
reconnect if no connection is available so the problem must be somewhere 
else. PostgreSQL connections themselves don't timeout but if the database 
is on a network and the connection is dropped then the DA may well think it 
is connected when it isn't. This is difficult to solve in the DA and you 
need to know why the connection is being dropped first.

Hi Charlie,

I was afriad of that. Looks like the firewall is killing it, and it is
not telling the DA.

Will need to speak to our network people.

Thanks for your help.
Cheers
Michael
