Do you mean latest forked process will have much higher priority to be selected on Linux? Didn't know that before.

But v8-profiler is stated as very experimental and I may need it to take snapshot and see which objects are likely leaking.

If I upgrade node to higher version and kill one child process not the cluster, does the new child process forked by cluster use the new node? > > -- > Job Board: http://jobs.nodejs.org/ > Posting guidelines: > https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines > You received this message because you are subscribed to the Google > Groups "nodejs" group. > To post to this group, send email to [email protected] > To unsubscribe from this group, send email to > [email protected] > For more options, visit this group at > http://groups.google.com/group/nodejs?hl=en?hl=en > -- >: ~ -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
