Last Modified: Feb 14, 2024

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

Known Affected Versions:
15.1.5,, 15.1.6,, 15.1.7, 15.1.8,,, 16.1.3,,,,,, 17.0.0,,

Fixed In:
17.1.0, 16.1.4, 15.1.9

Opened: Apr 21, 2022

Severity: 3-Major


Once a client connection fails, the var/log/apm log files get flooded with repeat error messages like "queue.cpp func: "printx()" line: 359 Msg: Queued fd"


The continuous error messages in the log files may cause high CPU issues.


When the client connection fails, for example, when the client connection is no longer valid, the log files are flooded with all queued connections which are available at that point of time.



Fix Information

Log level changed so that these logs are only printed in debug log-level.
