Hello guyz.
We are using Zato in Production. We are using image 0fca8e578b27 (from 2 days ago). We have enable hot deployment. And we update our services by pulling files from our Git Repo.
We have noticed there is a warning when zato reloads files

It seems like Zato does not close old file during a hot deployment. And because of that, we receive after a while a message Too many files opened.
Rvery time we need to stop and restart zato after that.
I have tried to incred ulimit but it doesn’t help. Does anyone know how to solve this pelase?
thanks for you help !!!
