I bet you didn’t limit the number of API trace entries. Try limit the number of
API trace entries that VPP keeps with nitems and give it a reasonable number.
api-trace {
on
nitems 65535
}

Subject: [vpp-dev] VPP Policer API Memory Leak
Hi Dear Developers,
I am testing creating and deleting of policers and it looks that there is a
memory leak
VPP Version: v22.10-release
My simple script:
#!/bin/env python
from vpp_papi import VPPApiClient
from vpp_papi import VppEnum
import os
import fnmatch
import sys
from time import sleep
vpp_json_dir = '/usr/share/vpp/api/'
# construct a list of all the json api files
jsonfiles = []
for root, dirnames, filenames in os.walk(vpp_json_dir):
for filename in fnmatch.filter(filenames, '*.api.json'):
jsonfiles.append(os.path.join(root, filename))
vpp = VPPApiClient(apifiles=jsonfiles, server_address='/run/vpp/api.sock')
vpp.connect("test-client")
r = vpp.api.show_version()
print('VPP version is %s' % r.version)
while True:
### Create 10 policers
for i in range (10):
name = "policer_" + str(i)
policer_add_del = vpp.api.policer_add_del(is_add=True, name=name,
cb=2500,cir=1000, eb=3000,eir=0,rate_type=0,round_type=1,type=1)
print(policer_add_del)
### Delete 10 policers
for i in range (10):
name = "policer_" + str(i)
policer_add_del = vpp.api.policer_add_del(is_add=False, name=name,
cb=2500,cir=1000, eb=3000,eir=0,rate_type=0,round_type=1,type=1)
print(policer_add_del)
The memory usage is growing permanently and very fast. It takes less than 10
minutes to spend ~ 100Mb of main-heap.
