Expected behavior

Do you have a repro? Is it related to erlang/otp#8510? If the code_server crashes there's nothing we can do besides restarting the VM

[PJUllrich]

Sorry, i don't really now. I'll close this one and will recheck it once the OTP bug is fixed. It if persists, I'll re-open this ticket. Thank you for your support! 💜

Fixed in erlang/otp#8744

[guess]

Is there any workaround for this issue until it's merged? Or is it just use OTP26 for now?
