Memory Full

[karthiknarayan]

I have a RP3440 machine with 16GB RAM,in which i have ORACLE9i and Tuxedo installed,

When i reboot the machine it works on fine,but after some days the memory gets fully occupied and in one fine day the machine fails to respond saying no memory available

if i use swapinfo command the memory used shows as 100% then if i restart the system again it works for some days and then the swap gets filled and the machine stops respoding, how to solve this isses

Hi,
keep an eye on long running programs that may have a memory leak and/or do not return memory.
Glance would probably be the tool of choice.

16Gb is a lot of RAM so the memory leak or runaway processes are pretty serious. Run this command several times a day to find the processes consuming RAM:

UNIX95=1 ps -o vsz,pid,ruser,args | sort -rn | head -20

This will show the largest 20 processes. Look for either the quantity of programs or incresing size to track down the problem.
