Timed out as no activity

My program subscribed to a topic, which received a lot of subscription information. After running for a period of time, the program would always report the following errors.

ERROR 2019-11-29 14:17:42 - 56480046-7dbd-4500-b074-b9e729a6d26c: Timed out as no activity, keepAlive=60,000,000,000 lastOutboundActivity=73,870,534,312,909,049 lastInboundActivity=73,870,474,311,957,613 time=73,870,594,312,986,154 lastPing=73,870,534,312,910,698
