Oops, in my first answer to this posting I made a mistake, and my correction got eaten (on a new machine I had a permission problem when mounting the encrypted partition with the TLS host cert used by the MTA...) So here's my "mea culpa" again. I said to divide the mem= size of the largest guest (512M for you, or 2^29 bytes) by 65536 (2^16), but this was wrong. UML's map zone size is 4096 bytes (2^12). Divide by that. In your case you get 131072 (2^17), compared to the default value of 65536 (2^16) in /proc/sys/vm/max_map_count. echo 131072 > max_map_count (or a convenient slightly larger number) and you should have no problems.
