Hi All,
I am using the riak with python/django.
Sometimes I am getting the error "Could not get response"
I am using Djang*o 1.5
Python riak-1.5.2
The error description is as follows;
*
Django Version: 1.5
Python Version: 2.6.6
Installed Applications:
('django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
)
Installed Middleware:
('django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware')
Traceback:

Exception Type: RiakError at /manager/camp-edit/EHbo24hFYDZGsg8ujpY9itDtM2a
Exception Value: 'could not get a response'
Any body please help me out to fix the above issue.
I see the riak source code
Moudle is at riak-1.5.2-py2.6.egg/riak/transports/http.py
The function where that is coming is as follows
def http_request(self, method, uri, headers=None, body=''):
"""
Given a Method, URL, Headers, and Body, perform and HTTP request,
and return a 2-tuple containing a dictionary of response headers
and the response body.
"""
if headers is None:
headers = {}
# Run the request...
for retry in range(self.RETRY_COUNT):
with self._conns.withconn() as conn:
### should probably build this try/except into a custom
### contextmanager for the connection.
try:
conn.request(method, uri, body, headers)
response = conn.getresponse()
try:
# Get the response headers...
response_headers = {'http_code': response.status}
for (key, value) in response.getheaders():
response_headers[key.lower()] = value
# Get the body...
response_body = response.read()
finally:
response.close()
return response_headers, response_body
except socket.error, e:
conn.close()
if e[0] == errno.ECONNRESET:
# Grab another connection and try again.
continue
# Don't know how to handle this.
raise
except httplib.HTTPException:
# Just close the connection and try again.
conn.close()
continue
# No luck, even with retrying.
raise RiakError("could not get a response")
At line number 626 in riak/transport/http.py
where http_requst is at http.RiakHttpTransport.http_request
This is error is coming very often. For what reason it is coming and how
to get permanent solution for this error .
