Any ideas what could be going on?

Did you run out of memory on the machine? How many penthouse job were you running simultaneously? You could try running one at a time and see if that resolves this issue for you.

If you run in docker make sure /dev/shm is large

Hi, fellows! Have the same issue and seems like I detected the root cause, but still have no competency to solve it. I use grunt-critical (which uses Penthouse). Several of our sites are hosted on a hosting which is designed special for Drupal sites and most of sites use CDN (CloudFlare). So seems like our "special hosting" has firewalls and etc... + CloudFlare of course has it ;) I mean, you know when you are trying to open some site which is covered by CDN, and you are seeing page with Google captcha in order to detect you are not a robot.

So these sites absolutely randomly meet the errors like these:

`Unhandled Rejection at: Promise {

Error: Protocol error (Runtime.evaluate): Session closed. Most likely the page has been closed. at Session.send (***/node_modules/puppeteer/lib/Connection.js:167:29) at ExecutionContext.evaluateHandle (***/node_modules/puppeteer/lib/ExecutionContext.js:52:77) at ExecutionContext.evaluate (***/node_modules/puppeteer/lib/ExecutionContext.js:37:31) at Frame.evaluate (***/node_modules/puppeteer/lib/FrameManager.js:211:26) at Page.evaluate (***/node_modules/puppeteer/lib/Page.js:582:43) at ***/node_modules/penthouse/lib/core.js:146:18 at } ` or `Unhandled Rejection at: Promise { Error: Page crashed! at Page._onTargetCrashed (***/node_modules/puppeteer/lib/Page.js:97:24) at Session.Page.client.on.event (***/node_modules/puppeteer/lib/Page.js:92:56) at emitOne (events.js:125:13) at Session.emit (events.js:221:7) at Session._onMessage (***/node_modules/puppeteer/lib/Connection.js:199:12) at Connection._onMessage (***/node_modules/puppeteer/lib/Connection.js:98:19) at emitOne (events.js:125:13) at WebSocket.emit (events.js:221:7) at Receiver._receiver.onmessage (***/node_modules/ws/lib/WebSocket.js:143:47) at Receiver.dataMessage (***/node_modules/ws/lib/Receiver.js:389:14) at Receiver.getData (***/node_modules/ws/lib/Receiver.js:330:12) at Receiver.startLoop (***/node_modules/ws/lib/Receiver.js:165:16) at Receiver.add (***/node_modules/ws/lib/Receiver.js:139:10) at Socket._ultron.on (***/node_modules/ws/lib/WebSocket.js:139:22) at emitOne (events.js:125:13) at Socket.emit (events.js:221:7) at addChunk (_stream_readable.js:265:12) at readableAddChunk (_stream_readable.js:252:11) at Socket.Readable.push (_stream_readable.js:209:10) at TCP.onread (net.js:598:20) } ` However, I tried to make some testings on my personal sites and on several regional large news portals which do not use any firewalls and CloudFlare (do not use any CDN). In that case the errors have never been! **How I test:** 1. Sites on a special hosting + CDN. In that case the error can appear randomly, even if there is only one URL and one request (not a bunch of URLs in an array/queue), so right at 1st URL. 2. My personal sites and a regional large news portal. In that case errors have never been seem, even if I use bunch of URLs (home pages and inner pages both) and have a set of 100-200 URLs per one test (foreach form 100-200 urls)

@srtfisher , what is the way and platform you are running penthouse in? MacOS, Ubuntu, Vagrant or Docker? Seems like I found the cause (for Docker case). Local in Windows 10 and under Vagrant (with Ubuntu 14 x64) it is always fine for me, whereas our project is in Docker and it is always f..cking random failures there (page crashed, session closed, etc...).

The same issues and complaints were found a lot of where: https://github.com/GoogleChrome/puppeteer/issues/1321 https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md#running-puppeteer-in-docker https://bugs.chromium.org/p/chromium/issues/detail?id=736452 https://bugs.chromium.org/p/chromium/issues/detail?id=715363 https://github.com/c0b/chrome-in-docker/issues/1

Result: I have increased the RAM of my Docker container and now there are no any random errors.

Seems like this was about insufficient memory allocated for penthouse/chrome, on the machine. Will close the issue, for now.

Will re-open if someone comments, if the problem still exists and memory doesn't explain it - please test on the latest version of Penthouse first though!
