[BlueOnyx:11171] Unable to load dynamic library '/home/solarspeed/php/lib/php/20060613/pgsql.so

[Dr. Blunt]

I just did a YUM update then received:

Active Monitor has detected recent changes in the state of your server 
appliance.
For more details, please see the Active Monitor section of the Server Desktop.

Summary of changes:

* The CPU is being heavily used. This will result in noticeable performance 
loss. Consider moving some of the services to other servers, or reduce the 
complexity of the CGI scripts running on the server itself.

I checked tail -f /var/log/httpd/error_log

PHP Warning:  PHP Startup: Unable to load dynamic library 
'/home/solarspeed/php/lib/php/20060613/pgsql.so' - 
/home/solarspeed/php/lib/php/20060613/pgsql.so: undefined symbol: 
php_regcomp in Unknown on line 0

I did an internet search on this error and found what I thought was a 
partial solution which was to re-boot. Did that however -- errors are still 
showing.

Any suggestions appreciated.
David.
