You could check several things:
Having var at 90% should not be an issue. No idea what isql does but from googling I guess it's just a SQL java client to issue some SQL on a box. Is the database in that case running on the same box or a remote box? You might have to check if the issued runs are different in execution etc. ie. if table scans occure that because of a now missing index or something like that. Need a bit more info about your infrastructure, what you are doing with isql etc. and which app is on which box etc.
The 0.1% to 0.3% should be really no issue. If your box has no room CPU wise for 0.2%, then there you have another big general problem.
And make vmstat running - it is very helpful.

You could check several things:
- Make sure your box has no general performance problem. This can be achived with running topas or vmstat (get it working!
) instead of just iostat since they give much more interessting info on virtual memory (paging space in/outs etc.), kernel thread queues etc... - Make sure there is no other jobs running at this time in parallel which were not running in the days before when everything was fine.
- Set up nmon and nmontools (nmon2rrd) for long term monitoring (free available via IBM websites). With the tools you can generate nice looking reports in form of html sites with good formatted graphics so it will be easier to identify in a short time, if there were any obscurities in the different runs, like other processes running in parallel which are not supposed to be there and so on.

genrbox
GENBOX(1) General Commands Manual GENBOX(1) NAME genrbox - generate a RADIANCE description of a box SYNOPSIS genrbox mat name xsiz ysiz zsiz [ -i ][ -r rad | -b bev ] DESCRIPTION Genbox produces a RADIANCE scene description of a parallelepiped with one corner at the origin and the opposite corner at (xsiz, ysiz, zsiz). The sides of the box will be parallel to the three coordinate planes. The surfaces that make up the box will be modified by mat and their identifiers will begin with name. The -i option can be used to produce a box with inward directed surface normals. The -r option can be used to specify the radius for rounded edges. The -b option can be used to specify the indentation for beveled edges. EXAMPLE To produce a rectangular box made of wood with beveled edges: genrbox wood box1 5 8 3 -b .5 > box1 AUTHOR Greg Ward BUGS Because spheres and cylinders are used to construct boxes with rounded edges, a transparent box of this type appears quite messy.
