Hello Shubham, I tried setting swap to 8GB, but the result is the same... the box gets int= o state that I can't login to it even after few hours, so hard reset is needed.. When I have top started, I see a lot of memcg_process_stress processes. What is strange, when I start the test with swap disabled, memcg_process_st= ress processes just seem to eat all physical memory and then just sleep. OOM killer doesn'= t kill anything, but the box doesn't hang.. weird.. I'm wondering whether to report this to kernel list? or do You have any idea on where to look? cheers nik > > Thanks, > Shubham > --=20 ------------------------------------- Ing.
