     Type:  defect (bug)        |     Status:  new
 Priority:  normal              |  Milestone:  Awaiting Review
Component:  Networks and Sites  |    Version:  4.6.1
 Severity:  normal              |   Keywords:
  Focuses:  multisite           |
--------------------------------+-----------------------------
 Setup:
 - Pretty slow server running php 5.5 (As a result calling wp-
 admin/upgrade?step=upgrade_db might take several seconds in average.)
 - PHP max_execution_time is 30 seconds. Value can't be changed by scripts.
 - WP-Multisite with about 400 blogs.

 Reproduction:
 - Call wp-admin/network/upgrade.php?action=upgrade
 - Result: Network Upgrade gets stuck at some point, terminating with http
 error 500
