When we had our major problem last time I found an appid that wasn't experiencing the problems and moved the whole application there. I kept monitoring the bad instance for about 3 weeks after and it was still getting hit the same time each day.,
I haven't bothered to look at it since. On a side note, it looks like app recycling has moved out to between 4 to 6 minutes. Which means if you run something like django and it fails during the initial imports you get a stuck instance that just barfs continously and won't die unless everyone stops trying to access it and it gets rec-cycled. If recycle time has gone up from around 1-2 mins to 4-6 minutes its going to be a lot harder to get rid of stuck instances. As a matter of course I now always to deploy 2 copies of the same code (version-numnber-a and version-number-b) and if one version gets stuck we will flick the default version to the alternate one. Unfortunately this hasn't worked at alll today as the quiet version won't start up either because of DeadlineExceeded errors. So app engine has been very flaky for me today (12 hours) and there is zip I can do about it. I am starting to get some heat over this (ie was it wise to chose appengine). Hopefully we can attract some attention from a google person. T On Sep 1, 9:25 pm, Kyle Jensen <[email protected]> wrote: > Thanks for your note Tim. > > Crap -- that is very concerning.
