[Rspamd-Users] Neural bug after upgrade to 2.6

[Christian Balzer]

The train limits are also being ignored in local.d/neural.conf, the redis
definitions not though:
---
  servers = "172.16.50.81"; 
  train {
    max_train = 3k; # Number of trains per epoch
    max_usages = 60; # Number of learn iterations while ANN data is valid
  }
---

log:
---
2020-10-07 18:04:53 #27008(normal) <935d89>; lua; neural.lua:414: skip ham sample to keep spam/ham balance; too many ham samples: 1001
---
1000 being the default in the lua script.

this worked before of course:
---
2020-10-06 06:25:31 #22035(normal) <e4c445>; lua; neural.lua:478: cannot learn ham ANN default:default; redis_key: rn_default_default_qeipi9xa_851: too many ham samples (3001 vectors stored)
