Hi,
I am using Akka with work pulling pattern (producer-consumer) in my
application. (Ref -
https://github.com/MartinKanters/java-akka-workpulling-example)
I have single producer and multiple consumer. My machine has 16 cores and
32 threads cpu. The number of consumer is configurable.
When I give more than 8 consumers then everthing works fine. But as soon as
I lower that number to 4 then a issue comes in
Issue -
* Java HotSpot(TM) 64-Bit Server VM warning: INFO:
os::commit_memory(0x00007f2136580000, 514326528, 0) failed; error='Cannot

* executor = "fork-join-executor"*
* fork-join-executor {*
* parallelism-min = 2*
* parallelism-factor = 2.0*
* parallelism-max = 64*
* }*
* throughput = 5*
* } *
Can you tell me what can be the cause of this issue? Please Help !!
