Under certain condition opening ZIM (homepage) gives a black screen about apple

[BPerlakiH]

What I meant was, this system warning that we are running low of memory, since Kiwix is in the background it takes a lower priority for the system, and the system will start to "free up" memory.

I will come back with a more direct plan, once I try out a couple of ideas, and see which one is working for this scenario.

Actually I have a reproduction case, it happens if I try to reopen (after closing its tab) a ZIM file if Kiwix went on hibernation.

@BPerlakiH @mgautierfr @rgaudin To me here we face a similar root cause like #772. I believe the core of the problem might be that if the app is hibernated and then resumed, the filedescriptors are lost. Could we try to confirmnthis theory?

So far I have found that if the Kiwix app is in background, and there's a genuine low memory error on device, after which foregrounding the Kiwix app, it will have this error, when we try to re-open a tab.

Which error? What would be your proposal?
