Hi All,
we are using apache ignite 2.7.6 with pesistence enable inside Azure
Kubernetes cluster in production.
we have 2 pods having persistence enable, The pods have below resources
assgined to it
CPU : 3 core
heap: 3 GB
Peristence : SSD 15 GB
WAL : SSD 5 GB
We are reading / writting throigh JDBC thin clinet. The client are outside
of kubernetes, so they connect through kubernetes LoadBlancer IP.
The loading data part (from PostGres to Ignite) is quite OK, and it runs as
scheduled.
But we are facing below issue(Null pointer exception) when the clients are
trying to connect through jdbc thin client. Once the issue occurres, ignite
triggers a complete restart, so clients are not able to connect that time
and everything goes for toss.
We never faces this issue in lower enviornment. We are stuck with the issue,
request help on thios.
