Failure to concatenate furthermore when using mkvmerge without ulimit

[Simulp]

I forgot to set ulimit -n 99999 before av1an is done encoding on (Arch) Linux, this is the result:

thread '<unnamed>' panicked at 'assertion failed: !self.chunk_queue.is_empty()', av1an-core/src/broker.rs:110:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

no matter what I do, I can't resume it. It will just keep spitting out the error message. The current seemingly solution to this is manually summoning mkvmerge and inputting options.json.
