kern.dfldsiz on my machine does not influence.
I don't believe you can change that value after the system has
booted-- you have to set it either in the kernel's config file, or
in /boot/loader.conf, for this to actually take effect.
I.e. after booting I run
$ limits
and it shows me the old 500M.
Now, a point about 'maxdsiz'= 3.0-3.5G instead of 4G - this one I
must check.
I tried 3.9G :)
Try using 3GB, agreed.
Also, please note that the dftdsiz keyword affects the "hard" limit,
not the "soft" limit...your shell might well have 500MB "soft" dsize
limit by default, but would permit you to change that upward to the
maximum set by the "hard" limit once you've changed that value.
See "man getrlimit":
A resource limit is specified as a soft limit and a hard
limit. When a
soft limit is exceeded a process may receive a signal (for
example, if
the cpu time or file size is exceeded), but it will be allowed
to con-
tinue execution until it reaches the hard limit (or modifies
its resource
limit). The rlimit structure is used to specify the hard and
soft limits
on a resource,
struct rlimit {
rlim_t rlim_cur; /* current (soft) limit */
rlim_t rlim_max; /* maximum value for
rlim_cur */
};
Only the super-user may raise the maximum limits. Other users
may only
alter rlim_cur within the range from 0 to rlim_max or
(irreversibly)
lower rlim_max.
