[Mono-list] Npgsql

[Carl Olsen]

Actually, I tried a remote connection using putty and it timed out.  That
gave me a clue that it's Apache or Linux and not necessary the Npgsql.dll
file giving me a problem.  I've started to add several assemblies to the web
site and referenced them from the global.aspx.cs file, which means it can't
find some of the pieces.  That could easily be the problem.  I rebooted the
server and now the entire web site is broken.  I'll have to finish what I'm
doing and then check it again.

Thank you!

Carl

Well that sounds like the SQL call you are making is taking an 
exceedingly long time. Have you tried running the same call using psql 
from the command line, or from within the PgAdmin3 GUI to see how long 
the SQL actually takes to execute? You can increase the timeout on your 
connection object within your code, but that's really just avoiding the 
problem. What exactly is your code doing? Can you post a snippet of both 
the SQL you are using, and the code that creates the connection object 
and executes your SQL? I might be able to shed a bit more light on the 
issue then.
