An unexplained memory peak triggered a cache flush.

We suspect a SQL server was slowed down for a couple of minutes, which triggered the global memory usage increase and then, the cache flush on http servers.

There's no easy way to prevent this snowball effect from happening with our current architecture.

This problem happened again on http6. We're still unsure about the root cause.

We've probably found the culprit.
