This has something do with your machine or server, not with ViaVersion

FormallyMyles commented 8 years ago

Use 0.6.7, closing issue. Request reopen if still occurs.

Issue is still here using 0.6.7

I think we have the same issue on our SkyWars server it would kept getting killed (by OS, due high load) ...

alexmarkey commented 8 years ago

Not sure what your issue is however we fixed this by not using your provided boss bar API, all servers have now been online for the past 24+ hours.

alexmarkey commented 8 years ago

Have the following information that may help you guys out in resolving :)

Our only server that didn't crash using your API was our Creative server, only thing that Creative has that's different is players don't die on it, server that crashed the most was kitpvp, players die a shit load in Kitpvp, so im assuming something is going wrong when resending the packets after they die? not sure.

@alexmarkey so does it work just without using bossbar API?

alexmarkey commented 8 years ago

We are currently just using this API https://www.spigotmc.org/resources/api-bossbarapi-1-7-1-8-1-9.7504/ for the 1.8 boss bar, then letting ViaVersion convert it and that is working fine for us.

The crashes occur when using the boss bar implemented into ViaVersion :)

Will continue to investigate overviewed our code and can't find a cause but it may be easy in other code to cause this using concurrency elsewhere. Will reopen if I find more cases.
