Hi,
I found a strange thing in zk 3.5.6 that sometimes
observers ignored one get children req (local session). thougth other watch
events could still be sent to the involved c++ client. Then the involved
client waited the get children reponse for totally session timeout time and no
ping could be sent to observer until the session expired. The client said
"invalid zhandle state" 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 ?
