OpenCore Webserver stops responding

Morphyum · October 15, 2025, 8:17am

OpenCore version: 1.5.12.20

selfhosted

From time to time when working with opencore the websites just goes offline. wss keeps working but the page is not reachable anymore, till we restart.
We found no problem in any traefik or other routing and could track the error down to the container.

the only error in the logs that i can see as maybe relevant is this:

RangeError: offset is out of bounds at Uint8Arrayset () at messageParserwrite (file:///app/dist/public/server/chunks/authsvelte-JsmrF6VOjs:3631:21) at wsonmessage (file:///app/dist/public/server/chunks/authsvelte-JsmrF6VOjs:3822:20) at callListener (file:///app/dist/public/server/chunks/module-CcjLScfgjs:10733:15) at WebSocketonMessage (file:///app/dist/public/server/chunks/module-CcjLScfgjs:10652:10) at WebSocketemit (node:events:524:28) at WebSocketemit (node:domain:489:12) at ReceiverreceiverOnMessage (file:///app/dist/public/server/chunks/module-CcjLScfgjs:12173:21) at Receiveremit (node:events:524:28) at Receiveremit (node:domain:489:12)

Any idea what else we can check?

We saw that error shortly after we launched the new interface. It happened when you request too many items in one of the data views, so to combat it, we limited the max number of items per page to 100, as before.

I also saw it once, when the usersettings object becomes too big. So if you did not set max items per page to something big, try deleting your user settings (you can do it from the user menu where you also sign out).
