Upgrading the BrightCloud SDK from version 4 to version 5.36 requires a higher memory footprint compared to the earlier version. On low-end platforms that have 4 GB or 8 GB of RAM, there is limited memory for wr_urldbd. During upgrade scenarios, the daemon may require up to 1.8 GB of RAM and memory allocation may fail.
A continuous restart of wr_urldbd happens.
- Upgrading BIG-IP 15.x to BIG-IP 16.x or 17.x.
The wr_urldbd restart will not occur if the device has 16 GB of RAM.
If the system is less than 16 GB, BrightCloud SDK will not be intialized (cloud queries are disabled) and the wr_urldbd daemon will continue running to support the customDB feature.
