You should watch the size of your X server. Most likely, it, or Netscape's use of bitmaps on it, or Xerth's use of bitmaps on it, are the cause of a memory leak. You should consider using an X server that has been linked against Poul-Henning Kamp's new malloc, which is capable of sbrk'ing back to the system. > How could that eat up that much VM?

See which of the programs you are runnng cause it to grow. Potentially, update your X server to newer code (you may have to update FreeBSD to do this) or quit running the problem application. I syspect that if you are not running ahuge number of programs with huge memory requirements, that increasing the swap will only make it take longer to have the problem.
