Opened: Jan 17, 2020

Severity: 3-Major

Symptoms

The ntlmconnpool process continuously restarts after reinstalling the license. The system reports a message in the BIG-IP console: Re-starting ntlmconnpool. The BIG-IP may show as 'Disconnected', and 'TMM outbound listener not yet created' messages may be present in /var/log/ltm.

Impact

The system requires a reboot and reports a ‘Re-starting ntlmconnpool’ message continuously in the BIG-IP console.

Conditions

This occurs when you upgrade your license such that the new license changes the number of available TMMs.

Workaround

To resolve the issue, it is necessary to reboot. Once the system restarts, it operates as expected.
