Opened: Mar 22, 2017
Severity: 4-Minor

Symptoms

When running the 'tmsh show sys tmm-info' command from the command line, you may notice that the utility returns memory information only for the main thread of each TMM process. All the memory available to the TMM process is accounted for under its main thread, and all other threads appear as having no memory at all. For example: # tmsh show sys tmm-info --------------------------- Sys::TMM: 0.0 --------------------------- Global TMM Process Id 18228 Running TMM Id 0 TMM Count 1 CPU Id 0 Memory (bytes) Total 17.0G Used 522.9M CPU Usage Ratio (%) Last 5 Seconds 2 Last 1 Minute 2 Last 5 Minutes 2 -------------------------- Sys::TMM: 0.1 -------------------------- Global TMM Process Id 18228 Running TMM Id 1 TMM Count 1 CPU Id 1 Memory (bytes) Total 0 Used 0 CPU Usage Ratio (%) Last 5 Seconds 2 Last 1 Minute 2 Last 5 Minutes 2 [...]

Impact

This issue is cosmetic, and there is no functional impact to the BIG-IP system. Whilst a BIG-IP Administrator may find the output confusing, all TMM threads have an equal share of the memory and are operating correctly.

Conditions

This issue occurs on any BIG-IP device running version 11.3.0 or later (provided that TMM threading has not been disabled for troubleshooting purposes).

Workaround

Refer to memory information for the main thread.
