Lotus miner can not seal because of memory

[metalgear-dev]

Hello, everyone. I'm very interested in filecoin. And I want to implement it with lotus framework.
Now I'm using lotus with version 1.13.2. I use 128G RAM and swap with 256G.
But when I seal the sectors, error occurs like "sched: not scheduling on worker ea70b111-3c34-4af1-b27b-3a7fdca4f2db for withResources; not enough physical memory - need: 176808M, have 128847M"

There is a github closed issue like this one.
filecoin-project/lotus#2109
And there, some one said that this issue had been already closed in the following url.
filecoin-project/lotus#2155
FFI version was the problem(Update to 0.30.2). But I'm using FFI with version 0.30.4
How can I deal with this error?
If anyone who can help me deal with this error, please let me know.
