Bug Details

Priority: 3-Major
Status: Not Verified
Impact Category: Application Security Manager

Description

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.
