Python couchbase client exception

[Yago Riveiro]

Hi,

I'm trying to load 500K docs in a couchbase cluster, I have shards
with 100k docs, each shards is loaded via same python script
The three first shards were loaded without any issue, but the fourth
shard reported this error

Exception in thread dispatcher-thread (most likely raised during
interpreter shutdown):
Traceback (most recent call last):
File "/usr/lib64/python2.6/threading.py", line 532, in
__bootstrap_inner
File "/usr/lib64/python2.6/threading.py", line 484, in run
File "/usr/lib/python2.6/site-packages/couchbase/
couchbaseclient.py", line 661, in _start_dispatcher
File "/usr/lib/python2.6/site-packages/couchbase/
couchbaseclient.py", line 968, in dispatch
File "/usr/lib64/python2.6/Queue.py", line 174, in get
<type 'exceptions.TypeError'>: 'NoneType' object is not callable

Now when I execute the loader script I have always this issue

Someone have idea what this could be?

Thanks
