<3>[  271.170013] Out of memory: Kill process 1729 (enigma2) score 836 or sacrifice child

What are you doing that makes a high-end box like that run out of memory?

Hello and thank you for lightspeed reply.
I do nothing extraordinary. There is installed just few plugins and softcam ( oscam-emu latest) from feed.
Maybe in some case oscam restart with unknow command ant restart also the box gui. It is possible every restart generate a new instance of oscam and fill up the ram ? Just ask a dunno. Thank you

I doubt Oscam is causing this, it tends to be very stable.

 

Login to the box with telnet, and enter the command "top -m" to show memory usage. Make a screenshot and post that here so we can have a look.

That could not cause an "out of memory" (RAM), but an "out of disk space" in flash.

 

The interesting bit in the log is:

<4>[   34.552876] oscam-emu invoked oom-killer: gfp_mask=0x200da, order=0, oom_score_adj=0

which suggests that oscam-emu is eating up all memory, as it already crashes after 34 seconds. 

 

Is that the oscam-emu from our feeds? ECM cache active?

In all cases it is the OOM killer that terminates Enigma due to lack of memory.

 

That is unlikely to be a bug, something is running on that box that eats up all available RAM, either on it's own, or as a plugin in Enigma.

 

The only two I know of are the ECM caching in Oscam (if configured wrong it can use large amounts of memory) and EPG in Enigma (which is all stored in memory). Having said that, the UE 4K is a modern box with tons of memory...

 

I would start with flashing the box again, do not restore a backup, do not install any plugin, just watch some FTA channel, and see what happens. If it remains stable, install the softcam, and check again. If it remains stable, install the first plugin from your list, repeat, until you have found the culprit.

Hello and thank you for support. I made some check&fix on my config. ECM cahce =15s and bad CW is drop not loged or stored but other interesting   config is about oscam stream relay  wich was on  now it is disabled. EPG is just for future nothing stored for past.

I will test with new settings and come back  with  feedback after few days, Again thank you for valuable support.

I meant flash the box with the latest image, do you restore or autoinstall anything, configure the box by hand, and one at the time add the softcam and plugins, to see what is causing the problem.

Three possibilities to get an OOM

 

- software with a memory leak, wasting memory

- a driver bug, leaking memory (but then everyone using that model should have the same phenomenon), these are really hard to spot, nothing seen in user space

- ramdisk getting full

 

The last one is quite easy to spot, using "df -h /tmp".
