Crashing in DRAM mode

[bhcsayx]

Hi I am trying to run fastswap in DRAM mode, the process of installing patched kernel and loading modules was successful, but I got a crash when trying to run quicksort benchmark, the crash happens in copy_page() of sswap_rdma_write() in fastswap_dram.c and related information retrieved by gdb are shown below:

The $rdi value does seem suspectable, but I have no idea on why this is happening. Wondering if any suggestions from you and many thanks in advance!

What's the size of your swap partition, and the size of the DRAM buffer?

Below is htop result, my swap is 2G

I did not modify my DRAM buffer size, so I think it's 32G the default value
