On Linux low entropy can cause certain operations to be very slow.
SSL operations need entropy to ensure randomness. Entropy is generated by the OS when you use the keyboard, the mouse or the disk.
If an SSL operation is missing entropy it will wait until enough is generated.
Do you see a slow start of your weblogic managed server for forms & reports on unix derivate? We have this problem on Suse SLES 11 and forms and reports 11.1.2.
