Hi,
Our application all of a sudden throws errors that I've not seen before.
While we continuously deploy new minor features, we've not made any
substantial changes that would explain either of these:
* Datastore access misbehaving:
Nested in javax.servlet.ServletException:
com.google.apphosting.api.ApiProxy$ArgumentException: An error occurred parsing
(locally or remotely) the arguments to DATASTORE_V3.Get().:

* com.google.appengine.api.memcache.MemcacheServiceException: Memcache put:
Error setting single item (_ahsahRx7dGRBNmJh6XPmzlfTg) -- This one is
thrown so deep inside the bowels of Jetty that it's outside our
application's reach, and thus a memcache error takes down our application
once again: http://code.google.com/p/googleappengine/issues/detail?id=6463
* URL fetch throws errors we've not seen before:
Caused by: com.google.apphosting.api.ApiProxy$ArgumentException: An error
occurred parsing (locally or remotely) the arguments to URLFETCH.Fetch().
Also, memory is all of a sudden rising a lot, every now and then. Resetting
the instance with the most instances helps for a while, but the problems
resume a few hours later. I'd be tempted to think that the memory issues
can cause some of the above errors (but not all).
It's been a while since 1.7.0, so I wouldn't be surprised of this is
related to internal 1.7.1 testing. If this is the case, please stop and
move us back to a regular 1.7.0 environment.
Cheers,
Per
PS: I've raised production issues, but since I have never heard back from a
single one *ever*, I'm posting to this forum to state how unhappy I am. It
seems to be the only way to get attention (yeah, I've tried getting premium
support, but it's not available in Germany...)
