Dear gentlemen,
i am using freebsd 3.4Stable and i got it freezed after trying to copy
the contents from 2 directory and from CDROM to a single directory, the
command i issued was:
cp /xxx/yyy/* /tmp &
cp /xxx/zzzz/* /tmp &
cp /cdrom/* &
The contents of this three directory is about 250 files and 1GB of data.
Just after issued than, i decide to watch my system using the top
utility, it was ok, but one thing drived me crazy.
Althought the proccesses was not increasing its memory usage, the amount
of available memory was coming down and down, until the time i were
prevented from forking a single ls, due to the following message at
console: swapper: out of memory.
My question is: if not proccess was eating more memory which part of the
system was eating all my 128 MB of memory? The situation get so terrific
i could not even halt or poweroff my system, i had to turn it off by
hand.
How can i prevent my user from hanging my system? I am sure there some
way to control this.
Can any one point me a solution?
Here goes some useful information:
