Every time the policy server starts or a connection to the Policy store needs to be opened (e.g. with test connection function of smconsole) the policy server pauses for a couple of minutes and no connections are opened.

The RedHat OS distribution provides an RNG (random number generator). Two devices are available for this:
The /dev/random will block and wait for more entropy when the entropy level (something like the 'amount of randomness) is too low while the /dev/urandom will not block, returning immediately. There is no question that using /dev/urandom is less secure, however, this vulnerability is only in theory and there is no known cases or ways to abuse this in the non classified literature.
See for example the following page on the Red Hat Academy web site (1). As mentioned there, "though not truly random, the numbers generated by /dev/urandom are still thought to be cryptographically secure. "
Entropy is generated by various ways (keystrokes, mouse moves, disk i/o etc). Unless used really heavily, /dev/random should NOT run out of entropy. There have been many bugs in this area with RedHat releases over the years (2).
To apply the workaround (change RNG), do as follow:
mv /dev/random /dev/origrandom
ln -s /dev/urandom /dev/random
