Edge SWG configured to continuously upload access logs to remote server
During periods when there are no access logs to upload proxy keeps the TCP connection alive by sending TCP keep-alives. Other devices such as firewalls may have a timeout which forces them to terminate the TCP session if that session is idle for too long (e.g. 3600 seconds).
Make sure that your firewall is configured to keep idle TCP session between Edge SWG and access log server alive for extended period.
