Close/reopen laptop lid - Brim shows Network error

[philrz]

This can be considered low priority, as it does not always happen. It's hard to reproduce and may be related to the size of ingested pcaps. Here's a screenshot of one time the problem reproduced:

More detail from the user who originally reported it:

When this happened, the ingest process stopped and I had to open file again and start over. I found the same problem when the screen saving/automatic lock of account happened.

I have tested this issue again with v0.5.4 and still happens.
I can easily reproduce now as follows.

1. Open big pcap file.
2. processing packets and progress bar
3. close lid and open again.
4. The ingest process stops and shows Network error message.

The errors I get looking at it with Developer tools are:

1. Failed to load resource: the server responded with a status of 400 (Bad Request)
2. Failed to load resource: net::ERR_NETWORK_IO_SUSPENDED
3. /Applications/Brim.app/Contents/Resources/app/dist/js/services/zealot/fetcher.js:218 POST http://localhost:9867/space/wrc12x.pcap.brim/packet net::ERR_NETWORK_IO_SUSPENDED 202 (Accepted)

I can see how the zeek process does not show in the system after this error.

Scope of this has been narrowed to simply improve the error message.

Good call.
I could reproduce if inactivity timer kicked in during an ingest.
But as a user installed the tool amphetamine ‎Amphetamine on the Mac App Store
https://apps.apple.com › app › amphetamine so that issue did not happen.

Thanks

Verified in Brim commit 8f8df0c talking to zqd commit 335d284. Following the original repro instructions, I closed the lid of my laptop during pcap import and it triggered the new error message.

Thanks @jameskerr!
