Description:
------------
After days of running, apache2.2.15+php5.2.14 fails in handling new requests.  By checking all httpd processes ,we found some httpd(s) were created very early and handles no
request (we set MaxRequestsPerChild to 10000) with the stack trace as
below(almost all threads are in lwp_park status). We have no idea what would be
the possible reason, the underlying OS is: SunOS Portal1new 5.10
Generic_141444-09 sun4v sparc SUNW,SPARC-Enterprise-T2000

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.

PHP 5.2 is out of support for quite some time now.
