Thanks again for the feedback. I've gone with 4.11.0+ git head kernels and last night rather than a lock-up I saw:
[40050.937161] mmap: chromium (6060): VmData 2148573184 exceed data ulimit 2147483647. Update limits or use boot option ignore_rlimit_data. [40051.183213] traps: chromium[6060] trap int3 ip:5642ccce7996 sp:7ffe0a563ac0 error:0
and the desktop session remained responsive.
The 2 GiB ulimit is preferable for me than having to rely on the OOM killer, but I can run tests with ignore_rlimit_data later on to check that the OOM killer still works rather than hitting some unforeseen error on swap exhaustion.
Arthur.
