Hmm.. I seem to remember that all previous RSS rlimit attempts actually fell flat on their face because of the reclaim-on-rss-overflow behavior; in the shared page / cached page (equally important!) case, it means process A (or container A) suddenly penalizes process B (or container B) by making B have pagecache misses because A was using a low RSS limit. Unmapping the page makes sense, sure, and even moving then to inactive lists or whatever that is called in the vm today, but reclaim... that's expensive... ------------------------------------------------------------------------- Using Tomcat but need to do more?
