i would not touch the task queues for such operations, tho. They are used by the map reduce when it calculates the shards for each segment of the map (maps using the index, assigning segments to shards - and the shards execute via task queue doing the reduce).
Probably you have a zombie job that is waiting for a shard to write into the datastore (these is how the shards communicate for some information) Anyways, glad it worked for you :) On 21 February 2011 23:51, Eric Ka Ka Ng <ngk...@gmail.com> wrote: > thx David!
