PHP4 stability and testing
We have 2 almost identical servers running uptodate Centos 4.x. One seems to be having stability issues with PHP (4.3.9).
We can't find any difference between the two systems. On one we have client reports of PHP having issues and we are experiencing random errors running Cacti - after a random time it will simply log us out.
Are there some PHP load/stress testing applications/scripts to see if our PHP install is stable? Or where might we begin to troubleshoot how our php install is causing issues?
