Crash "Error: ENOENT: no such file or directory"

[gigouni]

Hi,

Expected Behavior

When setting rotation file, it should not crash "randomly".

Current Behavior

Without knowing what happened, the logger crash. I'm using several projects with the same stack, the same Logger module but, when running during the night, some crashed and the other ones are still running (no crash of the logger).

I tried to resolve the problem and found this issue but it seems to be fixed since npm v5.4.1.

Here the report of npm doctor

Here two examples of the crash of the app:

# some correct logs here...
14:55:06.323Z INFO project_name: Database:: checkAuthToDb:: models synchronized successfully
# some hours later...
events.js:183
throw er; // Unhandled 'error' event
^

Error: ENOENT: no such file or directory, unlink 'C:\Users\ngigou\dev\apps\project_name\logs\project_name-error-2018-07-17.log'
00:00:00.423Z INFO project_name: Server index:: Closing connection with the server...
[nodemon] app crashed - waiting for file changes before starting...

or even (small difference, stat instead of unlink)

# some correct logs here...
14:55:06.323Z INFO project_name: Database:: checkAuthToDb:: models synchronized successfully
# some hours later...
events.js:183
throw er; // Unhandled 'error' event

Error: ENOENT: no such file or directory, stat 'C:\Users\ngigou\dev\apps\project_name\logs\project_name-error-2018-07-17.log'

Possible Solution

• Could it be a asynchronous issue when trying to rotate files?
• Some logs from previous days aren't zipped but some are (the days concerned by the crash), compression issue?
• Seen this issue but I really need to have two different files, is it impossible to split streams to different depending on the criticity?

Code

The Logger is imported as a node module (-> parentConfigPath) but can be run locally, without parent project (for dev usage).

import logger from 'my-logger-name'

lib/Logger.js

    this.options = this._getConfig()
    this.logger = bunyan.createLogger({
      name: this.options.LOG_FILENAME,
      streams: [

Thanks

Seems to be resolved when using only one file instead of two. Would be better to be able to split streams within different files depending on the log level.

Still waiting to be sure it's fixed. It's not because it didn't crashed yet that it's solved.

@Rcomian Clues about this issue?
