Hi,
I'm not sure if this is good netiquette, or not. I'm reviving a month-old
thread, because I'm trying to figure out how to resolve the issue.
To summarize: when I run unit tests with eclipse (and with Ant) on
Windows, at some point, I run out of available connections. I tried
increasing the maximum number of connections, but then I started seeing
the postgres server die and restart.
I'm trying to fix this, yet again, but I don't have a clear idea of what
to fix.

Does this allow creating more connections? At some point, the discussion
became too technical for me, and I no longer could tell if the answer was
for developers of for users.
I saw other messages dealing with semaphores/connection relations, etc.
But unless I really did not understand the discussion, none of them seemed
to address the issue I was seeing.
I'm thinking that the Java driver combined with Hibernate may be keeping
handles open for too long, because my tests aren't supposed to maintain
connections open for very long. I also would expect the connections to
either be closed or released once the statements are executed.
