MC-94554Zombie Pigmen Anger = Lag+Server Crash
Hello,
The bug I'm describing has been in the last 3 snapshots from what i can tell and causes the server to crash, when zombie pigmen become angry the world starts to lag and eventually causes the server to crash from overload, i checked this in single player and it also gets the lag.
Before the server crashes however you will get lag to the point where the zombies do not move they just kind of blink about to their destination, even falling zombie pigment will freeze mid air for a little while.
I checked with the server members and they also get this.
Thanks,
Night

Dupe of MC-94554
I'm confused, because MC-94554 (Zombie Pigmen Anger = Lag+Server Crash) is marked as a duplicate of this bug. But another bug MC-17630 (Zombie pathfinding to unreachable targets causes server lag), which appears to be the same issue, is not. For what it's worth, MC-17630 is definitely not fixed in 16w14a: zombie pigmans are freezing in midair still. If that is somehow a duplicate of this bug, that one should be closed and this one reopened, but I may be confused as to how or whether these three bugs are related.
The description of this bug is too vague for me to test, but MC-94554 which duplicates this bug (according to [Mod] redstonehelper) is easily verified to be still in 16w14a.
So do you think my zombie pigmans freezing in midair is a different issue? There's a bug MC-94554 which it might be instead, but that one is closed as a dupe of something else.
MC-94554 appears to be resolved by this update. Use of example world 1.9Fix-Ultimate-XP-Gold-Farm-bySnocrash no longer causing server to crash with the snapshot 16w14a.
The Zombies do move slowly while trying to track on you. When they figure out their paths you experience a strange speed up effect as they charge you. Then next batch spawns in and the process repeats. FPS remained at near 60 entire test.
Not sure how that relates to MC-94438.
I was actually voting for and following MC-94554 but it was combined in this bug report.
please provide the crash report
Here's the Crash Report
Dupe of
MC-63590Pigmen still lag like hell and instead of crashing that option keeps the server on but times you out instead, doesn't happen anywhere but when pigmen are angry... that other topic is just crashing so not sure how this is resolved and a duplicate..
MC-94582might describe your issue.That does not seem to be the problem, this happens in the nether and apparently in The End and not in the overworld, only happens to pigmen and seem endermen when they get agro it causes insane lag to the point the server times the player out, this never use to happen and i just did a test with the snapshots, 15w47c it's all fine but the moment i go to 15w49b it begins to cause lag and same happens for all snapshots above and before you say it's something wrong with the server or pc every single member gets this problem.
I keep getting links from you all which does not seem to go anywhere near the issue to the point you even put "resolved duplicate" this wasn't even resolved and it for sure isn't a duplicate.... pretty messed up.
Reopened.
It does happen on the overworld, https://bugs.mojang.com/browse/MC-94962
Acording to Panda https://twitter.com/Panda4994/status/681999441662885888 Is an AI issue about things not been able to get to you.
Single Player is also affected.
Confirmed for 16w04a
Confirmed for 16w06a.
I'm noticing a SIGNIFICANT improvement in 16w07a. I hesitate to say the issue is 100% fixed, because it sort of persisted, but after revisiting the chunk with freshly spawned mobs it seemed to be better (I tested this in my AFK gold farm, where the issue occured for me).
MC-94438fixed lag issues according to the changelog, so my best bet is that it fixed mob AI issues. The description says "Massive Lag in any snapshots post-15w47c", and the earliest version affected was 15w51b. I'm guessing this was one of the things that they targeted.Will do more testing in 16w07b.
