I got an alarm that my swap usage was up to 80%, which turned to be a fact when I checked topas.
The problems I've found were:
1) Looking into a vmstat 5 10, I found lots of PIs with 0 SRs. How's that even possible?

2) I went off to find who were consuming my precious memory and it I found that I actually know very little in how to figure that in a AIX.
Found this command somewhere which seemed reasonable reading the manual:
ps -ealf | head -1 ; ps -ealf | sort -rn +9 | head
which seemed reasonable by looking in the manual and gave an output of the sort:

Where SZ is supposed to be the size in 1k units, according to the man page; which also didn't make too much sense for these are Java processes with Xms=1G (or so) and as shown the biggest process has ~150mb. Again.. ?
And for the last, my server is not currently at maximum load but still shows ~20% of swap space usage. How do I explain that?
I'm pretty lost. These things were easier to figure with Solaris.
Would someone share some thoughts?
