We have a system with swap less than half the size I would like, 5 GB swap with 8 GB real. Last week we started to run out of virtual memory while real memory usage was still low. There was only 400 MB virtual memory remaining but 2 GB real memory available. What I'm curious about is if we run out of virtual memory will the system be affected or will it just start using more of the real memory. When I asked one person he said we could still run out of kernel resources and I asked him to elaborate but haven't heard back. If anyone can shed light on how the system would handle the situation I would appreciate it. Also we plan on rebuilding swap with 1.5 times real memory as a standard. Does anyone else have a standard they follow for allocating swap?

We are running on Solaris 2.9.

Thx, Dave
