Bug ID 1022493: Slow file descriptor leak in urldbmgrd (sockets open over time)

Last Modified: Feb 07, 2024

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

Known Affected Versions:
15.1.3,, 15.1.4,, 15.1.5,, 15.1.6,, 15.1.7, 15.1.8,,, 15.1.9,

Fixed In:
17.0.0,, 15.1.10

Opened: Jun 01, 2021

Severity: 3-Major


Unix domain sockets are opened and never closed in urldbmgrd. This is a very slow leak over time.


Urldbmgrd may hit a limit of open file descriptors, and may eventually core and restart. When urldbmgrd restarts, urldb also restarts. This may result in a momentary instant where URL categorization is not available.


SWG or URLDB is provisioned.


Restarting urldbmgrd will clear the open file descriptors. Performing a forced restart during a time of no traffic will mitigate the risk of urldbmgrd restarting at an inconvenient time if there are too many sockets open. "bigstart restart urldbmgrd" will restart the daemon.
