Dynamic VPN tunnel goes down at random and prompts for user name and password

Pulse VPN for SRX disconnects randomly and prompts for user name and password again.

Pulse is disconnected on its own. It prompts for user name and password again. The Pulse VPN tunnel goes down and connectivity toward the remote network also fails.

In Windows system, with Pulse debug log, we can see the following log message sequence. These log messages are collected in detailed mode.

When the Pulse Dynamic VPN (DVPN) phase 1 (IKE) security association timer expires, it is mandatory to re-enter the username and password to reform a new IKE phase 1 session.

This is the reason Pulse VPN tunnel goes down and prompts for user name and password.
