Bug ID 1561713: BD total_max_mem is initialized with a low (default) value resulting in many issues with long request buffers and traffic failing

Last Modified: Dec 31, 2024

Affected Product(s):
BIG-IP ASM(all modules)

Fixed In:
17.1.2

Opened: Mar 14, 2024

Severity: 3-Major

Symptoms

When BD starts it is assigned a very low value for total_max_mem

Impact

This causes many connections to fail with ASM resetting them.

Conditions

ASM provisioned

Workaround

Monitor "var/log/ts/asm_start.log" for the "F5::ProcessHandler::start_bd,,bd exec line" and see the value for "total_umu_max_size". If it is "768000" or there are other visible errors - restart asm on that device.

Fix Information

None

Behavior Change
