zlib error

[retouching]

Hello !

I have a problem with eris and zlib. Sometimes, zlib throw an error with "Error: zlib error -3: data error". I would like to know why this problem happend.

Error :

and my deps (include eris)

"dependencies": {
  "eris": "^0.14.0",
  "erlpack": "^0.1.3",
  "ioredis": "^4.19.4",
  "moment": "^2.29.1",
  "mongoose": "^5.11.19",
  "promise.any": "^2.0.2",
  "winston": "^3.3.3",
  "zlib-sync": "^0.1.7"
}

There have been a couple fixes since 0.14.0, does this still happen on 0.15.0? Are there any reconnects/connection issues around when this happens?

Yes, in my case it shows that error twice and then this

I'm using v0.15.0, but this error doesn't happen often. Also there aren't any reconnect issues when this happens.

I had the same error on the old InviteManager sourcecode ( https://github.com/SideProjectGuys/invite-manager-bot ) which used earlier eris versions.
It also happened a few minutes ago on our updated code ( https://github.com/LolRiTTeR/invite-manager-bot ) which is using eris v0.15.0
