| Jul 4, 2018 at 8:58 | comment | added | HopeKing | @mazs - in the link you provided (+1 for the great link), it says "To see how much ram your applications could use without swapping, run free -m and look at the "available" column. Now the OP has only 246M in the available column - But you mentioned in your answer that there is actually 6.5GB. Seems like there is a contradiction ? | |
| Jan 10, 2018 at 12:48 | comment | added | NickD | @mazs: OK - I see now that the OP is complaining about swapping and sluggishness (although he does not seem to be using much swap). But the unreclaimable memory in the slab does seem problematic. | |

| Jan 10, 2018 at 8:13 | comment | added | magor | @Nick it is counterproductive but if the OP wants to see the free memory at the available field, that's what he should do. I have not noticed the SUnreclaim amount....try to troubleshoot it with slabtop, updated answer | |

| Jan 9, 2018 at 16:01 | comment | added | Max Hollmann | I've tried that, it releases at most a couple of MB. Like Patrick says, it seems to be the slab, and I have no idea what that is or how to troubleshoot it. | |
| Jan 9, 2018 at 13:54 | comment | added | phemmer | Additionally the provided meminfo shows that the memory is sitting in slab unreclaimable, so this won't do anything anyway. | |
| Jan 9, 2018 at 13:31 | comment | added | NickD | Just to be clear: freeing the various caches is counterproductive. It will "improve" the numbers and perhaps make the OP feel better for a little while, but the caches will be repopulated with time and everything will go back to the way it was before the caches were freed: that is normal. Unless there is some other indication that something is wrong, it is best to leave this alone. | |
