java - App engine new instance every request -


i'm using google app engine jersey (1.17). got 0.5-1 request/sec (max).only 1 instance run automatique scaling (frontend).
1 april goes crazy, every request new instance start. think start new version 1.9.2.

to resolve switch new instance management , set basic scaling 1 instance max.
problem :

  • non-automatic scaling run on backend
  • why new instance start every request


threadsafe , sessions-enabled activate.

thanks
