DO NOT REPLY [Bug 51059] New: Some httpd process hang on a strange
stack
https://issues.apache.org/bugzilla/show_bug.cgi?id=51059
Summary: Some httpd process hang on a strange stack
Product: Apache httpd-2
Version: 2.2.15
Platform: Sun
OS/Version: Solaris
Status: NEW
Severity: normal
Priority: P2
Component: worker
AssignedTo: bugs@httpd.apache.org
ReportedBy: zhannk@gmail.com
After days of running, apache 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

They are hanging in PHP code. Please open a report at the PHP website
(bugs.php.net).

Thank you, William, here're the libraries linked. It looks like all clib are
the same... we already raised a bug at PHP support site. the same application
runs well on a Solaris 9 box. This really goes weird.

It is a PHP issue... but note that these are all hung in the clib malloc/free
logic, so there is some internal clib mutexing that has become fluxored.
Make sure you didn't link up different clib/[mt]malloc libraries in PHP and
in httpd.
