It looks like your system is running with low entropy value.

Sufficient Entropy
On a Linux system, ensure that sufficient entropy is available. CA Identity Manager requires random data from /dev/random to perform essential cryptographic functions. If data in /dev/random is exhausted, CA Identity Manager processes must wait for random data to be available. This waiting results in poor performance. Use rngd and rng-tools to ensure that /dev/random has sufficient data and reading processes are not blocked.
Also refer this document also - Alternatives to renaming /dev/random to /dev/urand - CA Knowledge
Also make sure that you have installed, required packages.
CA Identity Manager Server
For Red Hat 6.x and Red Hat 7.x, install these packages in the following order:
- glibc.i686.rpm
- libXext.i686.rpm
- libXtst.i686.rpm
- ncurses-devel.i686.rpm
- ksh.rpm
libXmu.i686.rpm
libXft.i686.rpm
libXpm.i686.rpm
To monitor the entropy on the system, execute the following command:
watch -n 1 cat /proc/sys/kernel/random/entropy_avail
