Thanks, guys for suggestions.

I redid workload with slub_debug=F and collected /proc/meminfo, slabinfo
-S and /proc/pagetyinfo. It OOMed. Here are first few messages from OOM
killer and few last messages from proc files. During run collecting
script managed to wakeup once in 1-3 minutes. There are 12 minutes between
last and second-to-last messages which is I assume when X happened.
If needed, I can send complete writeout.

I'm going to add more swap now and make timings.
