Hi,
I have updated the config with 16G and session count 300000000
memory {
main-heap-size 16G
}
acl-plugin {
connection count max 300000000
}
But i am still seeing same crash i reported earlier. But now occurring less.
Is there any calculation as to how much sessions should be attempted for 16GB
or memory ? What's the max suggested values for session count for 64 GB system?
Here is the crash dump.
