DeadWorker when parallel processing about parallel HOT 3 CLOSED

parallel does not use lock mutexes afaik, so it's somewhere in your code ?
can you produce a simple example that I can use as testcase ?

from parallel.

Hi,

It is not consistent behavior. The context is inserting a lot of records in a postges database for a load test. Last run resulted in a Segfault...

The code basically does this:

    Parallel.each(array_with_ids, in_processes: 4) do |id|
      event_store = EventStore.new
      ActiveRecord::Base.connection.reconnect!
      begin
        event_store.replay_events_for(id)
      ensure
        ActiveRecord::Base.clear_active_connections!
      end

    end

The problems did not occur when running 1.9.3-p385, maybe it is unrelated to parallel but the segfaults and the error above do occur when running this process.

Versions:

• parallel (0.9.0)
• pg (0.17.0)
• activerecord (3.2.15)

from parallel.

Hi,

It doesn't seem related to parallel since not running parallel has the same effect.

Closing this issue.
