Many SQL request (postgreSQL)

Installation Issues

Hi,
I begin to investigate some freezes in kanboard and in house web applications (~30 seconds), all of them using postgresql 9.2 as backend.

I enabled logging in postgresql server and it appears that kanboard continually send requests to the server :

I don’t think this causes the freeze, but seems to be a strange behaviour
do you have an idea what these requests are? and how we can disable them?

Thank you

in config.php, put false to DB_RUN_MIGRATIONS stops this behaviour…

If you dont run migrations, you will eventually run into issues down the road, i.e. if you upgrade or install certain plugins.

thank you for your answer,
if I ugrade kanboard, it seems natural to manually ugrade the database schema too…I prefer that instead of having several thousand requests a day, all year long, for nothing.

As long as you are doing it, you are all good. Just wanted to make sure.

It’s not normal this create table attempts, even with run migrations enabled. I’ll take a look and see if I find a probable cause
