swap issues, system is running at 99%
Hi All,

I am trying to understand why my system is running at very high. This system is almost out of memory. See below.

Code:
swapon -s
Filename                                Type            Size    Used    Priority
/dev/mapper/VolGroup00-LogVol02         partition       8388600 8235088 -1

Code:
top - 04:56:23 up 125 days,  1:16, 150 users,  load average: 0.42, 0.36, 0.37
Tasks: 1141 total,   1 running, 1139 sleeping,   0 stopped,   1 zombie
Cpu(s):  0.3% us,  0.5% sy,  0.0% ni, 99.2% id,  0.0% wa,  0.0% hi,  0.0% si
Mem:   8161864k total,  6702472k used,  1459392k free,    42796k buffers
Swap:  8388600k total,  8235044k used,   153556k free,   855096k cached

Top shows that I have one zombie process but I was not able to find it? Any idea?

Code:
ps aux | awk '{ print $8 " " $2 }' | grep -w Z

zombie processes don't use memory, ignore it. Zombies are harmless unless they accumulate.

Look for what's using all the memory instead. Just ps aux | less and scroll through it.

150 user sessions can be one of the reason
