Summary: Running out of space in /tmp - (with one puzzle question at the end of this summary)
2007-12-24 21:49:00
Here's the summary:
Reason for the problem: There is some run away process that eats up all the
memory. I didn't find out which process before I reboot, I'll keep an eye
on it in the future.
Two ways to solve the problme without reboot:
1. use the swap command.
swap -l ->to show my swap slice.
swap -a /dev/dsk/c0t0d0s1 -> to add my swap slice
2. use mkfile then swap like this:
mkfile 500m /opt/swapfile
swap -a /opt/swapfile
(dont forget to delete it after reboot)
Afterthoughts:
my df -lk still looks weird.
here's my `swap -l` output:
swapfile dev swaplo blocks free
/dev/dsk/c0t0d0s1 32,1 16 1052144 1052144
but my df -k looks like this:
/dev/dsk/c0t0d0s0 490097 79444 361644 19% /
/dev/dsk/c0t0d0s5 3579989 843419 2700771 24% /usr
/proc 0 0 0 0% /proc
fd 0 0 0 0% /dev/fd
mnttab 0 0 0 0% /etc/mnttab
/dev/dsk/c0t0d0s4 482824 263233 171309 61% /var
swap 1010792 8 1010784 1% /var/run
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
swap 1010792 8 1010784 1% /tmp
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/dev/dsk/c0t0d0s6 3579989 2493988 1050202 71% /opt
I only have 513MB assigned for swap, and 640MB of RAM, why would I have two
swap spaces mounted on two place, /var/run and /tmp? Can someone tell me
when does /var/run get mounted? I dont have that entry in my /etc/vfstab.
thanx for the replies

--------------------
Hi, I have a urgent problem. My tmp space is running out. But it looks
like the server forgot to mount the correct swap slice. How can I change
this without reboot?
thank you
