FOSS gamedev and creative worlds

I have a strange problem with the server. At some point it starts to consume more and more RAM (from the usual 80M he got to 17G). I try to look at the trace (started server with --trace) and have just lines like: 4 <- 83.149.9.11:50225, size=63, data=63, data= 4F45 7403 0002 0001 0010 1972 6F61 6E31 316D 0000...

Can it be connected to player loading mods? It seems to happen when someone new tries to connect and load the music and mod data. Now I saw it just fixed itself after many minutes of memory leaks, and dropped memory usage to 100M. Strange.

Already posted an issue, sorry: https://github.com/celeron55/minetest/issues/346
