Hey there ! I finally upgraded from Pydio 8.0 to Pydio Cells, and it’s simply amazing ! Thanks a lot for your works. After two days, I finally managed to install Pydio with SSL and get Collabora Online running. Almost everything is perfect! I’m just having two problem : - when I start cells I get this error : > ``` > 2019-10-21T13:20:57.838+0200 ERROR pydio.grpc.user-meta could not initialise service at version 1.6.1 {"error": "Error 1062: Duplicate entry 'usermeta-tags' for key 'namespace'"} > 2019-10-21T13:20:57.838+0200 ERROR pydio.grpc.user-meta Could not run {"error": "Error 1062: Duplicate entry 'usermeta-tags' for key 'namespace'"} > > ``` And in Pydio, metadata don’t work. When I click on a file, there is always this error in the bottom of screen : Internal server Error. But all is working ! except metadata. If I disable metadata plugin, I don’t have these error message anymore. - and second problem, I sometimes have this message : > 2019-10-21T13:30:51.062+0200 ERROR pydio.rest.frontend Error while applying modifiers to registry! {“error”: “{"id":"go.micro.client","code":500,"detail":"Error creating stream: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = \"transport: Error while dialing dial tcp 192.168.1.28:34723: connect: connection refused\"","status":"Internal Server Error"}”} and when I browse to the home screen ( /welcome/ ) there is an infinite load and Internal server Error message. What can I do to fix that ? Thanks a lot, ---

Hi, 1st: What is db name and version you are using? 2nd problem: probably the ulimit, please increase this value, or use [systemd service](https://pydio.com/en/docs/kb/devops/running-cells-service-systemd) ---

Hey and thanks for your help. I’m using MariaDB v 10.3.17. I already increased the ulimit by nano /etc/security/limits.conf - soft nofile 16384 - hard nofile 16384 But I will try by starting cells as a service 🙂 ---

Hi @lubovic If you end up with connections errors, your machine may be undersized, or the ulimit setup is too low. What’s your VM size? (cpu/ram). Can you check `ulimit -n` for the pydio user? ---

Hey charles! ulimit for the user running pydio is 16384 in soft and hard. Pydio Cells is running on a zotac box at home, dedicated for that. i5 4210Y ( dual core ) with 4gb ram. Thanks for your help and all of your work. ---

I hope I’m not spamming… But I have new problems ☹ When rebooting system, cells launch succesfully with systemd, but it don’t work. Stuck on the gray page loading. In logs I have : > 2019-10-24T14:22:11.828+0200 ^[[31mERROR^[[0m ^[[32mpydio.rest.frontend^[[0m Ladon validation failed: {“id”:“go.micro.client”,“code”:408,“detail”:“context deadline exceeded”,“status”:“Request Timeout”} {“error”: “{"id":"go.micro.client","code":408,"detail":"context deadline exceeded","status":"Request Timeout"}”} If I just > sudo systemctl stop cells > sudo systemctl start cells Then it’s working nice ( except the problem with the metadata ) and error above don’t show again. Still have this error, showed in first topic : > 2019-10-24T14:22:11.828+0200 ^[[31mERROR^[[0m Error while applying modifiers to registry! {“error”: “{"id":"go.micro.client","code":500,"detail":"Error creating stream: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = \"transport: Error while dialing dial tcp 192.168.1.28:35457: connect: connection refused\"","status":"Internal Server Error"}”} Any advice please ? ---

Hi, It’s strange. Do you have any security settings such as limit of process, selinux? ---

Nope… I don’t understand, really looks like that is limited but every where I take a look, it’s not limited. I have a new problem : when playing with big files movies ( 60gb ) I can’t move them, rename or sync data. > 2019-10-30T13:59:51.858+0100 ^[[34mINFO^[[0m ^[[35mpydio.grpc.data.sync.personal^[[0m 2019-10-30T13:59:51.858+0100 ^[[34mINFO^[[0m Cannot compute checksum for films.mkv {“error”: “not.implemented”} ---

Hey all ! I did a fresh install of debian, and pydio too. I specified the ulimit even before download pydio… and now, all is working fine ! Now I’m testing the 2.2. Thanks a lot for all your advice.
