Description:
With Cassandra 4.0.x, we are seeing this message very frequently on the
majority of our Cassandra 4.0 clusters:
_[INFO ] [epollEventLoopGroup-5-3] cluster_id=99 ip_address=127.0.0.50
NoSpamLogger.java:92 - Maximum memory usage reached (128.000MiB), cannot
allocate chunk of 8.000MiB_
It took me several weeks to track down what it means, until I saw this start-up
message
_BufferPools.java:49 - Global buffer pool limit is 2.000GiB for chunk-cache
and 128.000MiB for networking_
This maximum memory usage warning would benefit from clarifying that its the
{*}network cache{*}, not the *off-heap chunk* *cache* which is exhausted. With
'chunk cache' in both warning messages, they're too easily confused.
