MPLS Packet Loss

Question

Hi,
I have an issue problem on one PE (PE-3), if I doing test from the neighbor or another PE to PE-3 using "ping mpls pseudowire <loopback PE-3> <VCID>"  and ping using vrf to PE-3 there is many packet loss, but ping test to loopback PE-3 is normal no packet loss.
anyone ever had an experience like this?
PE-1#ping mpls pseudowire xxx.xxx.xxx.130 10001 repeat 1000
Type escape sequence to abort.
Success rate is 94 percent (278/295), round-trip min/avg/max = 1/3/48 ms
PE-2#ping vrf TEST 192.168.9.2 repeat 1000
Type escape sequence to abort.
Sending 1000, 100-byte ICMP Echos to 192.168.9.2, timeout is 2 seconds:
Success rate is 92 percent (260/281), round-trip min/avg/max = 1/2/16 ms
Ping to loopback PE-3
PE-2#ping xxx.xxx.xxx.130 repeat 1000
Type escape sequence to abort.
Sending 1000, 100-byte ICMP Echos to xxx.xxx.xxx.130, timeout is 2 seconds:
Success rate is 100 percent (1000/1000), round-trip min/avg/max = 1/2/100 ms
PE-1#ping xxx.xxx.xxx.130 repeat 1000
Type escape sequence to abort.
Sending 1000, 100-byte ICMP Echos to xxx.xxx.xxx.130, timeout is 2 seconds:
Success rate is 100 percent (1000/1000), round-trip min/avg/max = 1/2/52 ms

Hi Gilang,
From description and diagram, Am I assuming right that 192.168.9.2 is configured on PE-2?. if so, I think the comparision should be between L2VC ping and ICMP ping to x.x.x.130.
Can you share the configuration from PE-1?. Do you have any CoPP or QoS enabled?. L2VC ping is not ICMP based and uses 127.x.x.x address as destination. So they are a bit different with L3 details in header (though it is a ping to same address).
