As long as your assigned swap is equal or more than your physical RAM, its safe..
I cant assist you without much info..
1.Use mkfile to create a file suitable for a local swap area. For example, to create a 1GB swap file:
/usr/sbin/mkfile 1024m /swapwhere /swap is the name of the file to be used as swap space. Units for the size can be kilobytes (k), blocks (b), or megabytes (m).
2.Tell the system to start using the file as swap:
/usr/sbin/swap -a /swapUse
swap -l to verify that the swap file has been activated.
Put an entry in /etc/vfstab also.

mkfile
mkfile(1M) mkfile(1M)
NAME
mkfile - create a file
SYNOPSIS
mkfile [-nv] size [g | k | b | m] filename...
mkfile creates one or more files that are suitable for use as NFS-mounted swap areas, or as local swap areas. When a root user executes
mkfile(), the sticky bit is set and the file is padded with zeros by default. When non-root users execute mkfile(), they must manually
set the sticky bit using chmod(1). The default size is in bytes, but it can be flagged as gigabytes, kilobytes, blocks, or megabytes, with
the g, k, b, or m suffixes, respectively.
-n Create an empty filename. The size is noted, but disk blocks are not allocated until data is written to them. Files created with
this option cannot be swapped over local UFS mounts.
-v Verbose. Report the names and sizes of created files.
USAGE
See largefile(5) for the description of the behavior of mkfile when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
