Heap out of memory when reading events from file (50,000 tests)

See original GitHub issue

Running a massive set of tests, I get this:

  51973 passing (5h)

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

The contents of file .solcover.js:

module.exports = {
    port:           8555,
    norpc:          true,
    testCommand:    "node --max-old-space-size=8192 ../../node_modules/truffle/build/cli.bundled.js test --network=coverage",
    compileCommand: "node --max-old-space-size=8192 ../../node_modules/truffle/build/cli.bundled.js compile --network=coverage",

@barakman Modified your issue title to disambiguate your case from the one we already advise about in the FAQ.

I don’t know how to fix this. If anyone has any ideas, please weigh in.

@cgewecke: You’re welcome. This one in specific has been both exhilarating and excruciating to investigate and resolve (well, workaround)… As a matter of fact, in terms of difficulty, I believe that it was second to Truffle 4 issue 729 only. Thank you for providing this outstanding tool, which IMO is a must in every Ethereum project. Happy New Year 😃
