What steps will reproduce the problem?

1. Find a zombie spawner. In my case, I had built an exp farm around it.

2. Watch the zombies spawn ^{refer to explanation below}

3. The majority of the zombies will despawn seconds within spawning.

What is the expected output? What do you see instead?

The expected output is that, as per the config, the zombies will spawn up to a maximum of 50- thus even if I go afk for hours there will still be 50. Instead, however, I often see no mobs at all.

A player stood directly below the spawner (which is located in chunk 129 1 -227, while the landing area is in chunk 129 1 -226) and the zombies spawned while I watched in spectator mode. About 90% of the time the zombies will consistently despawn within seconds of spawning. When the zombies despawn, they will do so for a consistent period of time before functioning again- and if they don't despawn, they won't despawn for a while.

Standing in a different chunk within spawn range does not appear to have an effect.

I have also included my Dynmap plugin version below, in case it is related to a chunk load bug documented here (introduced in 1.9) that potentially orphans entities during the load/unload process required to generate the map.

What version of the product are you using? Plugin Version: ClearLag v2.9.0

Spigot Version: git-Spigot-a1b8bf3-f01861f (MC: 1.9.2) (Implementing API version 1.9.2-R0.1-SNAPSHOT), using Java 8 64bit

Dynmap Version: core=2.3-SNAPSHOT-2071, plugin=2.3-SNAPSHOT-1136

Do you have an error log of what happened?

No errors in console.

Please provide any additional information below.

Seems to be related to #125, where poster has a similar problem with spawner generated spider mobs.

Changed markup type to wikicreole.

Good ticket.

I changed up the mob-spawner limiter a bit to:

A: Continue to limit mob-spawner even if the chunk is unloaded - and reloaded (Unless you chose to remove mobs on unload),

B: Use slightly more unique hashes and do equals checks to insure no collisions.

Please get back to me on whether or not this build has fixed the issue. I've had another ticket related to this issue.

Sorry for the late response; I've had a busy week and finally have time to test. The latest build (build #19) on your jenkins server creates a massive amount of console spam after server startup, using the same plugin config and spigot version as before. This is the message that is printed to console perhaps 3-5 times per second: http://pastebin.com/6tKUS1zW . Something I realized that I forgot to mention was that I also have WorldBorder, though that lies dormant and does nothing for the most part.

@ThgilFoDrol: Go

Small mistake. It's fixed in the latest build.
