Hello all,

We are running Solaris 9 on a V880 with 32 GB of memory
and 70GB swap.

Recently the system was very very slow, with a user process
taking almost all the main memory plus 60 GB of swap.

I want to limit the ammount of memory a user process
can take, to prevent that problem.

I tried to use "limit" to limit the memory size a user
can take, but above 4 GB solaris 9 sets limit to unlimited,
and I was thinking to limit the memory usage on a higher
level.

Any hints?

Thanks,

Joao

I don't know how (if) it can be done, but one way is a script run from
cron that kills off user processes using too much memory. Not very
eligant I must admit, but it would work.
