Hi, after kernel upgrade i've the following situation:
after 2 days of uptime: 08:41:41 up 2 days, 14:56, 0 users, load average: 13.07, 13.83, 13.65 size-192(DMA) 0 0 192 20 1 : tunables 120 60 8 : slabdata 0 0 0 size-192 35599 83060 192 20 1 : tunables 120 60 8 : slabdata 4153 4153 273 after 6 days of uptime: 08:41:41 up 6 days, 1:56, 0 users, load average: 16.60, 15.22, 14.48 size-192(DMA) 0 0 192 20 1 : tunables 120 60 8 : slabdata 0 0 0 size-192 1780288 1799240 192 20 1 : tunables 120 60 8 : slabdata 89962 89962 256 As you can see the size-192 is increasing and after the 7th days the server start swapping.
