100% Memory Usage
I have a V-Class with 5GB RAM, with a small 2GB disk swap volume. After a reboot, glance shows me at 100% memory usage, and 90% swap usage, running a Progress database. This is something new within the past few days. I am stumped as to the problem. The only thing I can think of is that maybe the swapmem_on parameter. Any thoughts?

Re: 100% Memory Usage
The swapmem_on parameter will not effect the memory usage as glance sees it. Are you REALLY swapping? What does swapinfo show?
The first thing to do is drill down into glance further and see what processes are running that are eating your memory.

Re: 100% Memory Usage
Have they added some new instances?
This could be normal. How close were you watching it before the reboot?

Re: 100% Memory Usage
First, of course, what's changed? Posting the output of 'swapinfo -tam' would be helpful. Do you see memory pressure with 'vmstat -S'?
If you have 'glance', looking at its memory statistics is helpful, too.

Re: 100% Memory Usage
maxswapchunks = 16384
swapinfo: type=dev (1%) type=memory (82%) type=total (89%)
vmstat shows 0 for 'po'
glance shows 99% Mem Util, 89% Swap Util

Re: 100% Memory Usage
So if you use -B 1000 and the blocksize of the database is 2048, then the memory consumption is 1000*2048
This could have become a problem due to an incorrect Buffer (-B) or if someone has rebuilt/loaded the database with a larger block size.

Re: 100% Memory Usage
One adjustment I'd make is to reduce the buffer cache ceiling ('dbc_max_pct') from 20% (which in your configuration translates to about 1GB RAM) to something like 5-8%. I'd set 'dbc_min_pct' to 2% at the same time. You should see a noticable improvement in memory utilization.
Regards!
