VPS moved new node -> php memory usage dropped. Why?

[cits]

I recently had Support move my VPS to a new node.

There was no downtime and existing long-running PHP scripts were unaffected. I noted that the memory usage of these scripts dropped from typically 10M down to 2M.

I had need to restart one of those PHP scripts and observed the memory usage of that script was back to 10M.

The questions... What caused the memory drop for the running scripts and how am I able to get any new starts of the script to have this reduced memory footprint?

Thanks

Only their support staff can figure that out after logging into your server..

Laurie,

The drop in this would've been probably a side-effect of the transfer. For you to restart it and it be back at 10M indicates that the process didn't play nicely with the migration most likely.
