They periodically (every 3-4 months, = sometimes earlier) create a core dump under /var/fm/fmd.
Looks like fmd core dumped, so no email = notice is sent, and we end up filling the rpool.
I found  this link: https://support.oracle.com/knowledge/Sun%20Microsystems/= 1020519_1.html
So here I = attach the pstack of one of the dumps.
 
Any = idea?


fmd_alloc(= ) does panic when we are out of memory:

    =     if (data =3D=3D = NULL)

                = fmd_panic("insufficient memory (%u bytes needed)\n", size);


You can try adding some more swap space = perhaps?
