HornetQ VIRT keep on increasing to more than 9G (for both HornetQ 2.2.5 & 2.2.8)

[yannywang]

I've seen this situation for both HornetQ 2.2.5 and 2.2.8.

When the server is up and has messages sent to and consumed from, the VIRT (seen in TOP on linux) will keep on increase to more than 9G and it's still on-going.

the RES only increased from 3.3g to 3.8G while the VIRT increased from 4G to 9G.

any idea why this happens and how to reslove this issue?

The HornetQ we use is standalone non-cluster version.

are you using Netty NIO? Paging?

[yannywang]

yes. I'm usig paging and netty nio.

Here is my configuration:
