Memory Leak

MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 interactionCreate listeners added to [Client]. Use emitter.setMaxListeners() to increase limit

I recently got this error, my bot only has 2 slash commands and 4 context menus, which are not used much, I already asked in the djs server and they said to go ask here instead

Could you show the stack trace?

I already rebooted the server so the errors were cleared, however it also displayed this: Error: Opening handshake has timed out

Lioness100•16mo ago

What's the stack trace for that

Lioness100•16mo ago

Maybe you have too many awaitMessageComponent calls you didn't add a time property too for auto-clearing

-Carlos👑OP•16mo ago

none of my slashes or context menus uses that also i've been running slash commands and context menus for a while and I cannot replicate the error, could be a host issue?

Lioness100•16mo ago

I'm out of ideas without the code or the full error

-Carlos👑OP•16mo ago

if I ever get the error again I will create another post and if I remember correctly in the error there were a lot of Error: Opening handshake has timed out probably 10+

Hey @🠷Carlos👑, sorry to Necro, did you ever find the cause of this? I'm in a similar spot with one of my bots running now. Only had a handful of slash and context commands. It's been running fine in a production state for months. Opening handshake has timed out

This is not a memory leak. Nor is it an error. As the first word says, it's a warning. A 2 second google gives many results such as https://stackoverflow.com/questions/49946001/nodejs-maxlistenersexceededwarning. You either ignore it, or you set the max listeners to a higher count. As for the "Opening handshake has timed out", that is not Sapphire related and could be argued isn't even DiscordJS related. As the stracktrace shows, this is an error that comes from the ws (websocket) library and TL;DR just means the websocket fails to complete a handshake with Discord's servers. This could be a deeper networking issue on your server's end, an issue on Discord's end, or anything in between. Also, again there are many similar posts online: - https://stackoverflow.com/questions/61860024/connection-to-socket-gets-error-websocket-opening-handshake-timed-out-using-ja - https://github.com/websockets/ws/issues/1574 - https://github.com/discordjs/discord.js/issues/9571
