x670V-48x multicast L3 hardware table full

Hello,

At a customer we are using 3 stacks of 3 x670v-48 switches.
These are configured native stacking.
The multicast used is PIM Sparse mode.

In the log file I keep seeing the following message:
Slot-2: IPv4 multicast entry not added. Hardware L3 Table full.
When checking the L3 hash table using the following command:
show iproute reserved-entries statistics
I see a total of 357 entries, when the Theoretical maximum is at 4096.
The firmware we use on the switches is 15.4.1.3

Does this entry in the logs indicate a problem with the ipv4 multicast configuration?
If so, what impact does this have on the streams?
