No swap space to grow stack
Dear Solaris Experts,

I had a Problem with swap consumption in our Production server.
I found error message in /var/adm/message:
Code:
Aug  1 10:55:40 production genunix: [ID 470503 kern.warning] WARNING: Sorry, no swap space to grow stack for pid 29716 (oracle)

What should I do for temporary solution? I need no downtime for the temporary solution..

Really appreciate for any idea..

You can either free some virtual memory (eg: big files in tmpfs based file system) or add more swap space (swap -a xxxx). The simplest is to use a swap file.

Top 10 files|directories in /tmp:
Code:
du -sk /tmp/* /tmp/..?* | sort -nk1 | tail

Top 10 processes:
Code:
ps -eo pid,rss,vsz,comm | { read line; echo "$line"; sort -nk2 | tail; }

Should be "sort -nk3" in that case as the system was out of virtual memory, not out of RAM.

Hi,

server is out of swap memory.

You need to increase the swap online if you have space in your volume group

Add the disk and create a swap file
