My largest Sidekiq application had a memory leak and I was able to find and fix it in just few hours spent on analyzing Ruby's heap. In this post I'll show my profiling setup.

As you might know Ruby 2.1 introduced a few great changes to ObjectSpace, so now it's much easier to find a line of code that is allocating too many objects. Here is great post explaining how it's working.

I was too lazy to set up some seeding and run it locally, so I checked that test suite passes when profiling is enabled and pushed debugging to production. Production environment also suited me better since my jobs data can't be fully random generated.

So, in order to profile your worker, add the sidekiq_profiler.rb (below) to your project

Adjust number of jobs you want your worker to process before you have heap dumped.
Run a sample worker: PROFILE=1 sidekiq -C config/sidekiq.yml and wait for jobs to be processed.

// run this inside the javascript console of the Backups page:
urls = $x('/html/body/div/div/div[4]/table/tbody/tr//a')
urls.forEach(function(e) { console.log('curl "' + e.href + '"' + ' -o "' + e.innerHTML + '"') })

// It will output a ready to use list of wget commands that will download every backup file
// If the console adds line numbering or other useless data like in chrome, try this instead:
urls = $x('/html/body/div/div/div[4]/table/tbody/tr//a')
var wget_list = ""
urls.forEach(function(e) { wget_list = wget_list + 'curl "' + e.href + '"' + ' -o "' + e.innerHTML + "\" \n" })
