Hi,
I found a strange thing in zk 3.5.6 that sometimes
observers ignored one get children req (local session). thougth watch events
still was sent to the c++ client. Then the client waited the get children
reponse for totally session timeout time and no ping could be sent to server
until session expired. The client said "invalid zk handle" after session
expired.
The issue's frequency situation:
A) 1 to 5 get children requests are
ignored per minute when: 6000 client is connected to one observer,
zk_packets_sent 2M/min, zk_packets_received 1M/min;
B) and less get children requests are ignored
when lower zk_packets_sent and zk_packets_received.
I caught packets for the journey, no one reponses for the ignored get
children req when it occurred.
Why sometimes get children req.s were ignored ?
Is it possible a bug in zk3.5.6 ?
