google app engine - Why GAE launched a second instance with Max Idle Instances set to 1 -


i use google ap engine billing status enabled.
idle instances set : ( 1 – 1 )

enter image description here

and 2 clients on service, saw second instance. trouble it's take 15s launch new instance (spring , co..).

enter image description here

80mb of memory hight 1 instance ?
log new instance : /_ah/warmup 200 14580ms 0kb
second instance disappears after few seconds.

why 3-4 requests, gae run second instance ?? first 1 nothing (almost) !

i tried modify "pending latency" without success.

a solution ? :)

thx

you've asked 1 idle instance. when serving request, instance not idle. therefore, app engine spins new instance maintain requested number of idle instances.
