More info. I can duplicate this issue on every instance I have that I yum update to all the latest packages on centos 7.x. They all exhibit this same behaviour. I am running strongswan 5.7.1 and centos:
[root@ip-100-97-48-212 ~]# cat /etc/*-release CentOS Linux release 7.6.1810 (Core) NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/"; BUG_REPORT_URL="https://bugs.centos.org/"; CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7" CentOS Linux release 7.6.1810 (Core) CentOS Linux release 7.6.1810 (Core) Hosts on centos 7.4.x do not exhibit this issue.

Please verify sender before opening attachments or clicking on links. I have an issue with a tunnel where the tunnel is up, but after some time incoming traffic stops flowing. All traffic is initiated from the remote end. In order to get traffic flowing again I have to initiate some traffic to the other side. Any ideas why this might be happening and how to correct?
