Opened: Nov 27, 2019

Severity: 3-Major


For each message dropped during GENERICMESSAGE_INGRESS, memory is leaked.


As more memory is leaked, less memory is available for message processing, eventually leading to a core.


Usage of GENERICMESSAGE::message drop iRule command during GENERICMESSAGE_INGRESS event will leak memory.


Use MR::message drop during MR_INGRESS event instead to drop a message.

Fix Information

Usage of GENERICMESSAGE::message drop iRule command no longer leaks memory.
