I'm unavailable until Tuesday my advice would be to get profiler and attempt to work out what brings it to this cause, possibly turning proper heap dumps on?
Vislo
@Vislo
Mar 21 2016 00:09
core dumps?
Myles

The one which dumps mem if it has a crash like that yeah

but is not like memory leak issue sometimes it happes after 3 minute uptime. The memory which is free is a lot. Is a fatal error exception caused by writing something in the packets.
all the hs_err_pid files say the same
same thread
J 14765 C2 io.netty.buffer.AbstractByteBuf.writeBytes(Lio/netty/buffer/ByteBuf;I)Lio/netty/buffer/ByteBuf; (71 bytes) @ 0x00007fd6df61c996 [0x00007fd6df61bb40+0xe56]
always says this is the last thing he is doing. in the thread
JavaThread "Netty Server IO #3"
that crash report is generated because of a fatal exception who made the server crash
not a OUT of memory thing

Not much I can say, I'd suggest turning on debug mode in server.properties and perhaps looking through a heap dump in a profiler to see if there is anything more you can get out of it

sure
but 100% is related to viaversion
anyways i dont really now how to read
that fatal crash logs made by JVM

Have you tried this on different hardware as a comparison? or with less plugins?
Vislo
@Vislo
Mar 21 2016 00:16
were trying with less plugins
but since we have viaversion on a lot of machines
them yes we tried in a lot of different hardware

Have you tried with different versions of spigot?
Vislo
@Vislo
Mar 21 2016 00:20
with paperspigot and normal spigot
so yes

Have you tried with a different version though? I haven't had any reports of this from any other server so it's something in your configuration which is different could mean it's our end.
Vislo

We're trying
different configurations

Is there a hacky way to provide 1.9 players a different server-texturepack/ressourcepack than 1.8 players? Because 3d texturepacks are broken for 1.9 and needs to be fixed. But when they are changed, they do not work on 1.8 anymore
Mats

you can send resource packs with PacketPlaySendResourcepack or something like that, just check if player is 1.8 or 1.9 and give them the right one
Maybe it's implemented in the spigot api, not sure though

Hello all,
Is anyone else experiencing a deadlock resulting from netty when using ViaVersion?
Myles
@MylesIsCool
Mar 21 2016 16:54
Nope, can you provide more info @Troctor
(like how to replicate / how to see this happen <3)

have to say PacketWrappers errors when it can't read things makes it so much nicer
one day we'll add pretty print errors :D

You mean because of this? :D MylesIsCool/ViaVersion@7d3e6bc

runs away
I only found it cause i was testing boats in the other version and accidentally switched then it told me couldn't read var_int
;)
I'm enjoying Jprofilers feature to group allocations by classloader (each plugin has it's own :'))

protocol lib has a bigger memory impact than viaversion on my test :O
