Thread: Frequently unable connecting to db "server doesn't listen"
If this e-mail address is not intend use for asking questions using e-mail suscription, please ignore it. I could not find any official PostgreSQL support forum for me to post ask questions. Appreciated if you could you refer me a few good PostgreSQL support forum for me to ask questions.
Problem:
The problem I am having has happened a few times within in a week. I am repeatly not able to connect to the db and having "server doesn't listen" message without touch anything, it just happen. First time it happen after I restarting my computer that has not been restart for almost a month. After restarting and trying to connect to DB and it failed, also I notice my computer can not be restart nor shutdown under the normal way by click on "start menu" and "shutdown or restart". I can only shut it down use the hard way by pressing the power button, I don't know why, but its another story. Therefore for DB, I only can fix it by uninstall and reinstall PostgreSQL. But it happening repeatly.
Any one experience it? or to guide me to where I can find help?

Several possibilities. What's your max_connections set to? What does the postgresql log have to say (if anything) about these failed connections? How many postgres processes are running when this happens? What OS is this on? Are you using some kind of persistent php client? Or some other kind of pooling client that might be using up all the connections? Any other info you can give us will help.

After the DB was shut down the hard way it will probably be in recovery mode the next time you start it. You can't connect to the DB while it's in recovery mode. I think the first thing you need to focus on is to find out why you can't shut down your system normally. If you can't find a solution for that, at least stop the PostgreSQL service (I'm guessing the name, I don't have PG on my game box) before you press the power button. > Therefore for DB, I only can fix it by uninstall and reinstall > PostgreSQL. But it happening repeatly. Reinstalling shouldn't be necessary, it's probably enough to wait until recovery is complete. The logs can tell you what's going on.
