asyncio_redis and aioredis error on getting a list of keys - python-asyncio

Question

When I try to get values for a list of keys using asyncio_redis or aioredis, I am getting the following error. I know it is about something python socket, but unable to resolve the error. I attached both the code and error log with this issue. Here keys are a list of large byte arrays. get_params_redis is called by multiple processes. Any help would be appreciated, thanks!
async def multi_get_key_redis(keys):
redis = await aioredis.create_redis_pool(
'redis://localhost')
result =[]
for key in keys:
result.append(await redis.get(key))
# assert result == await asyncio.gather(*keys)
# return result
redis.close()
await redis.wait_closed()
print(result)
return result
def get_params_redis(shapes):
i = -1
params=[]
keys = []
for s in range(len(shapes)):
keys.append(s)
values = asyncio.get_event_loop().run_until_complete(multi_get_key_redis(keys))
for shape in shapes:
i = i + 1
param_np = pc._loads(values[i]).reshape(shape)
param_tensor = torch.nn.Parameter(torch.from_numpy(param_np))
params.append(param_tensor)
return params
