Re: Virtual memory exceeded in new

Hi Randa,

You can run ps and look at the field "SZ", which gives you the number of a 
process' swappable pages currently in use. To find out about the size of one 
page, simply run pagesize, which gives you the pagesize in bytes. Example on 
Solaris:


> ps -U chris -l

 F S   UID   PID  PPID  C PRI NI     ADDR     SZ    WCHAN TTY      TIME CMD
 8 S  2174 25488 25486  0  51 20 626f7338    246 626f73a8 pts/1    0:00 bash
 ...

> pagesize
8192

Therefore, my bash is using 246*8192 bytes of memory right now.

    -Chris.
