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

Last Modified: May 29, 2024

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

Known Affected Versions:
15.1.3, 15.1.3.1, 15.1.4, 15.1.4.1, 15.1.5, 15.1.5.1, 15.1.6, 15.1.6.1, 15.1.7, 15.1.8, 15.1.8.1, 15.1.8.2, 15.1.9, 15.1.9.1

Fixed In:
17.0.0, 16.1.3.1, 15.1.10

Opened: Jun 01, 2021

Severity: 3-Major

Symptoms

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

Impact

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.

Conditions

SWG or URLDB is provisioned.

Workaround

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.

Fix Information

None
