Occasional "Failed to get checkout info from our servers" error on checkout

[danieldaquino]

Occasionally the Purple LN checkout fails with an error pop up with the message: "Failed to get checkout info from our servers"

Looking at the logs I see intermittent error logs that cause the process to crash and restart.

Here is a rough stack trace:

• load_lnsocket(...)
• new LNSocket(...)
• Module._lnsocket_create(...)
• _emscripten_resize_heap(...)
• abortOnCannotGrowMemory
• Aborted(OOM)

Probable root cause

Resource leakage around the instantiation of LNSocket.

Fixed in 0ad77f6

Issue persists in production. There seems to be a second cause.

Created a more complete fix at e1c75dc. OOM crashes seem to no longer happen in production.

Closing ticket.
