Hi all:

my dpdk version is 21.11

1. Testing environment

[WRL-LTS22/LS1043ARDB]             [Spirent/TestCenter]
<eth0:fm1-mac1>          <======>  UDP 512byte, 256pps traffic rate, Total 35Mbps
<eth1:fm1-mac2>  <---> for network capture
<eth2:fm1-mac3>  <---> NFS root
<eth3:fm1-mac4>  Not connected
<eth4:fm1-mac5>  Not connected

|-- debug
|   |-- ipsecgw-add-debug-log.patch       Add debug log for dpdk sample 
|   `-- ls1043-secgw-debug.log            log file for ipsec-secgw
|-- fix
|   |-- example_modified_1018.patch       After applied this patch, it works good
|   `-- ls1043-secgw-modified.log         log for appled example_modified_1018.patch
`-- ipsecgw.cfg.1018                      ipsec-secgw config file            

when testing, after sometime, the network is down, and use the fix patch of example_modified_1018.patch, it works well.

if anybody met the same issue or anybody know the root cause of the issue.  If the fix is reasonable and  no other issues will arise ?

Thanks very much
