An excerpt from an email sent to the reporter. This should clarify the reason for the bug closure.
"
It is a complex failure of internal memory allocation routines deep within mono runtime. The bug is known to mono developers, however even them could not fix it[1]: they just disabled memory retrieval via mmap. Since this means that mono can't return allocated memory to the OS, we can't use the same workaround.
You can use either of the following two workarounds:
- either use il2cpp scripting backend, which does not seem to have this problem -- at least we could not reproduce it.
- refrain from excessive number of allocations.
If you are able to reproduce this issue on il2cpp, don't hesitate to reply, we'll investigate the bug further.
