Industry stopped working

[PetrOs]

Hi,

I got a following problem. I am playing OpenTTD 15.0 Beta 1 with a XIS Extreme industry GRF, now in year 2002. I got a following problem: I got a number of food-related industry objects near a large station (Abbatoir, Food processing plant). I have nearly 50 trains delivering the raw materials there (Livestock, Soy, Fruit, Packaging, several thousand units each a month) and several dozen ships bringing food and edible oil. When it was built, it worked perfectly. Now, trains arrive, and do not unload, despite the station showing that it accepts these cargo. No production happens, except for very rare cases, production graph shows short spikes of activity from time to time (maybe reacting on some specific trains?). Forcing the unloading (by setting unload and leave empty) just flooded the station with livestock.

What could be the reason?
Could it be related to renewal of trains, where I only exchanged the locomotives but left old wagons? I had such effect with trucks getting stuck with goods load at other factory, which was healed by total truck renewal (send to depot, sell, buy a new one)?

Im not familiar with that Industry set, but some Industry sets have an upper limit of how much you can take to them at any given time.
When this happens you have to stop sending materials to the Industry until it wants more.
Usually if you click on the Industry itself, not on the Station, it will tell you whether the upper limit has been reached.
