Description
After checking the log file, I noticed this error every few hours:
2021-03-19 03:02:12.701 [ERROR] [__root] [SHM] [-1-11:0x1cebab0] FATAL ERROR alloc2 cross large page boundary, offset: 30FFC00, size: 1072. You must remove all of the files in /dev/shm/lsmcd and restart the lsmcd server
The offset and size differ every time. What's causing it?

Research direction
Start with the reported log message and the shared-memory files under /dev/shm/lsmcd, then trace how the lsmcd server handles the stated offset and allocation size. Done means identifying the cause of allocations crossing a large-page boundary and documenting or verifying a fix that prevents the fatal error.
