"suspend" anomaly

System: UM 17.04
Machine: AMD FX8350 + RX480 8GB RAM

Symptom:

When first booted, memory usage ~700MB

After the first suspend/wakeup, memory usage slightly increased, no big deal.

suspend/wakeup again, memory usage increased to 2GB.

Subsequent suspend/wakeup cycles further increased memory usage to > 4GB. Eventually the system failed to suspend.

[quote=“ping-wu, post:1, topic:13331”]Subsequent suspend/wakeup cycles further increased memory usage to > 4GB.[/quote]Just to further investigate what exactly is going on here, could you try something for me? After the cycle has increased the memory use to such dramatic amounts, could you try logging off and on again?

So, not rebooting, just logging your user off and on again. And checking memory consumption after logging back on. Willing to bet it’s back to normal.

Thanx. I have gone thru several suspend/wakeup cycles w/o any problem.

What I did was to close Chrome before suspend. And, if the system memory remained above 900 MB, then I ran the following steps:

sync; echo 1 > /proc/sys/vm/drop_caches; echo 2 > /proc/sys/vm/drop_caches

So far so good.
