Bug ID	1364
Summary	telemetry conns may leak in certain situation
Product	DPDK
Version	unspecified
Hardware	All
OS	All
Status	UNCONFIRMED
Severity	normal
Priority	Normal
Component	other
Assignee	dev@dpdk.org
Reporter	1819846787@qq.com
Target Milestone	---

Every time the telemetry server su=
ccessfully returns from the accept, it
atomically increases the value of num_clients=EF=BC=88if < MAX_CONNECTIO=
NS=EF=BC=89 and then
executes pthread_create to create a thread to execute the client_handler
function. In this function, some information will be written to the client.=
 If
the write fails, the thread returns NULL without atomically reducing
num_clients, this will cause the Telemetry server to run for a period of ti=
me,
and the value of num_clients will be greater than 10, resulting in telemetry
being unavailable.=20
Therefore, the decrease in atomicity v2_clients should occur after the writ=
e()
failure
