My suggestions to use 1G hugepages and/or --single-file-segments were to
counter "Too many open files" error, which you should observe no longer.
"Out of memory" is a new error. What are the failing mmap() call arguments?
For example, if it uses fixed addresses, it may clash with the area
reserved by DPDK (also affected by --base-virtaddr). DPDK 23.11 should
consume less RES memory at startup since it doesn't map it all but on
demand. Does --legacy-mem option (which mimics the old babevior) affect the
crash?
