Hi,
since last week I am experiencing a very serious problem in my application.
Probably since I deployed for the first time after the new SDK 1.5.2 was
released.
The application is locking during 30 seconds (then it raises an timeout
Exception) just doing a single query. The query starts running normally during
a couple hours, then randomly starts locking, and after that almost all queries
like this lock. This is the query:
PersistenceManager pm = PMF.get().getPersistenceManager();
cmd = pm.getObjectById(Command.class, id);
I have also tried changing to this query:
PersistenceManager pm = PMF.get().getPersistenceManager();
query = pm.newQuery(Command.class, "id == idParameter");
query.declareParameters("Long idParameter");
query.setRange(0,1);
query.setUnique(true);
cmd = (Command) query.execute(id);
in both cases, it hangs in last sentence.
The persistence class is NOT marked as detachable.
The received exception is this:
com.google.apphosting.api.ApiProxy$ApiDeadlineExceededException: The API call
datastore_v3.RunQuery() took too long to respond and was cancelled
Can somebody help me with this? Is somebody experiencing this error?
