From: Operating system: Solaris 10 PHP version: 5.2SVN-2011-04-14 (snap) Package: *General Issues Bug Type: Bug Bug description:Php5.2.14, all httpd threads lwp_park
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 Portal1new% pstack 17315 17315:
