Pretty sure this is not related to my build, and the device had (after the crash) ~1.5GB free ram. An issue on so linked this error messages to leaked file descriptors, which is apparently intended in libsignal. The libsignal version i use has fixed that issue, but maybe there are other leaked FDs?

Steps to reproduce

• cannot (yet) reproduce, happened only once

Device info

Device: Xiaomi Redmi Note 3 Pro
Android version: 6.0.1
Signal version: 3.29.6 + Trolldemorted@cdb8ac2

It has happened again, but on a different device and with a different user and with an unmodified signal:

Nothing extraordinary happened, except that the device received a lot of receipts before it crashed.

i think i found the culprit!

signalapp/libsignal-service-java#40

[Trolldemorted]

was this fixed by signalapp/libsignal-service-java@0557122?
