I built a stock Solaris 10 VM in the lab a few weeks ago. After adding the fifth zone to it to host a NIS domain, it started suffering “out of memory” errors like the following:
May 3 14:30:59 sol10-a tmpfs: [ID 518458 kern.warning] WARNING: /tmp: File system full, swap space limit exceeded
May 3 14:31:53 sol10-a tmpfs: [ID 518458 kern.warning] WARNING: /zones/sol10-z5/root/etc/svc/volatile: File system full, swap space limit exceeded
May 3 14:32:10 sol10-a tmpfs: [ID 518458 kern.warning] WARNING: /tmp: File system full, swap space limit exceeded
May 3 14:32:34 sol10-a genunix: [ID 470503 kern.warning] WARNING: Sorry, no swap space to grow stack for pid 5650 (cron)

This is easy to fix if you know Solaris administration, but if not:
-bash-3.00# swap -l
No swap devices configured

This is a problem. The simple answer is to add more swap space, staring with a new disk to *host* the swap space. I added a 2GB thin-provisioned disk to the ESX VM, rebooted it, then ran the following:
-bash-3.00# devfsadm
-bash-3.00# format

yes, one of those is a blank line to accept the default cylinder “1”.
The info for this post was taken very directly from UtahSysAdmin.com. Huge thank you to Kevin for his post, which I needed to modify slightly to get my VM running.

EDIT: I am currently unsure if the last “echo” statement is right. After a recent reboot, swap wasn’t mounted untill I removed that entry from /etc/vfstab. Soliciting comments. Thanks!

I ran into a problem 2 years ago where I couldn’t remember the native packet capture tool for Solaris and couldn’t install tcpdump, so i thought I’d put down as many as many native packet capture commands as I knew, by OS, in a single place.  I’ll update this as I find more, since there’s hundreds of Operating systems out there.

Any others anyone wants added (or corrected), just comment or email and I’ll update this.
(Edit 7/29/08 – change tcpdump link)
(Edit 10/13/08 – add tshark info, thanks Jefferson!, and wireshark on Windows)
(Edit 2/23/2012 – repost since a DB problem lost this post.  Thanks wayback machine!)
