PA firewall dropping fragmented packets




We've seen Netflow Traffic being dropped by the Palo Alto firewall based on the packet captures taken. No zone protection profile is set. DF bit is set to zero. MTU settings are fine and fragmented packets are less than 1500. However, FW is not reassembling the packets. Global counter shows: IP Fragments entry insert failure. IP Fragements entry allocate fail.
How does one fix this issue?
Thanks in advance.
