Re: [SR-Users] Using AWS boto3 with KEMI Python routing scripts

Hi All, looking for some advice regarding the proper way to initialise an AWS API boto3 client object for send SNS messages within a KEMI Python 2.7 routing script.  I'm sure process forking has a major impact on how this works - from kamailio.cfg      fork=yes      children=4 -  but would greatly appreciate some guidance. I have tried various methods to allocate an client object self.sns_client = boto3.client('sns', region_name=MY_AWS_REGION)   1. within   __init__(), only once from module initialisation   2. on demand within a function call by any client code e.g. called from ksr_route_request(), each creating it's own client object  and so far all have resulted in intermittent crashes within botocore/client.py ultimately crashing thus : Core was generated by `/usr/local/sbin/kamailio -P /usr/local/kamailio/run/kamailio.pid -f /usr/local/'.
