[Wrapper-user] A Question About Wrapper Max Memory Settings

[<geo...@rb...>]

What happens when both the 'wrapper.java.maxmemory.percent' and the 'wrapper.java.maxmemory' settings are used?

Which setting takes precedence or do they work together?

Also the help files mention "memory thresholds relative to the amount of physical memory available on the system". Does available mean total installed memory or the amount of memory currently free? Does "physical memory" mean just the actual "physical" memory or does it include swap space?

For example, on a 64 bit system we have 32GB of memory, 30Gb of that free.

If wrapper.java.maxmemory is set to 4096M and the wrapper.java.maxmemory.percent is set to 90%; is the Java max memory set to 4GB or ~29GB (90% of 32GB) or ~27GB (90% of 30GB)?

If we now add a further 32GB of swap, giving a virtual total of 64GB of memory how does that affect things?

Thanks.
