Hi everyone, I install Pydio Cells2 on a Ubuntu 20.04 server, and i got some error when it running.

I put some details about the server, it’s 8c 2.1GHz-2.7GHz, 32Go RAM When pydio is down i got the message “There was a timeout while serving the request…” and i had to reboot it. ---

Hello, this kind of error generally shows a resource issue. Given the specs of your server (that are more than enough if 1. you don’t have many other apps that exhaust it 2. you have a reasonable number of users), I would have a look on the DB side. Did you change the max connection parameter ? Another idea, that might lead to this kind of issues: your server might have been running for a looooong time =\> you might have an old version. We improved things a lot in this direction lately (and fixed a few memory leaks) , so I would also advise you to upgrade to the latest 2.2.6 and see what happen. If both diagnose are wrong, please provide more details 🙂 ---

Thank for your answer @bsinou 🙂 I check and no i did’nt change the max\_connexion in mysql, what is the requirement for this parameter ? Is there other change to make in mysql for optimise ? I’m also going to upgrade in 2.2.6 Have a good day ---
