`cvs update -rrel-2-4-patches webwork (not sure if that is 2.4.7 or 2.4.5) on Centos 4.8`

After having used problemRandomize successfully in one problem I tried to install it in PGcourse.pl using the lines:

loadMacros("problemRandomize.pl");

ProblemRandomize(when=>"always",XonlyAfterDue=>1,style=>"Input");

ProblemRandomize(when=>"always",XonlyAfterDue=>0,style=>"Input")

if $studentLogin eq "admin";

# This gives the admin the ability to generate a new problem anytime?

When I went to test it by trying a problem (as admin) the server slowed way down to the point that I had to reboot it (I have noticed before that sometimes the one problem I have working will take a long time to load). Checking the logs here are some of the messages I had:

BEGIN_TEXT

The differential equation

$BR

\[y^{\prime\prime}+y = 0\]

has one of the following two parameter families as its general solution

$BR

\[

\begin{aligned}

y&=c_1e^x &y&=c_2e^{-x}\\

y&=c_1\cos(x) &y&=c_2\sin(x)\\

y&=c_1\tan(x) &y&=c_2\sec(x)\\

y&=c_1 &y&=c_2x\\

\end{aligned}

\]

$BR

Find the solution such that \(y(0) = $y0\) and \(y^\prime(0)=$dy0\): \{$soln->ans_rule(20)\}
