Operating Systems Solaris How can i find memory leak in Solaris? Post 302947574 by Peasant on Friday 19th of June 2015 02:40:51 AM

Try echo "::memstat" | mdb -kw"

I would suspect ZFS ARC cache has used most of the memory.

If that is the case, you can limit ZFS ARC cache in /etc/system (it will require a reboot).

For instance, added as last line in /etc/system set zfs:zfs_arc_max=4294967296 will limit the ARC cache to 4 GB.

You should consider this limit if you are running databases on ASM (real small arc cache).

Hope that helps
