I am sorry, I unfortunately got distracted by trying to finish some feature for the next release. And I must admit right now I have no good idea how to proceed. The pages that got dumped at least to me show no pattern that points to a certain process. You might be in a better position there since you know better what those instances are doing. The only vague suspect might be something that does asynchronous I/O (just because that would to a certain degree use anonymous pages which seem to be ending up on free lists incorrectly). If there was to be certain processes you would know to use aio and if that would be configurable, it would be worth trying to turn that off and see whether the instance survives. Or if there are independent tasks that cause some of the load and could be turned off and on, maybe it would become more obvious which direction to look. Though I doubt this is possible.
