Hi,
I am having a problem with starting apache, after successfully installing apache-jserv on our AIX 4.3.3 box. I have installed Jserv as a DSO with Apache.
I have
AIX 4.3.3
JSDK 2.0
JDK 1.1.8
Apache 1.3.12
Apache-Jserv 1.1.2.
I am getting a seg fault when I try to restart/start(apachectl start) apache with Jserv includes in my httpd.conf file. Specific error is not registered in any of the logs.
Here is the error
/usr/local/apache/bin>./apachectl start
./apachectl[71]: 30450 Segmentation fault(coredump).
/apachectl start: httpd could not be started
Changes in httpd.conf

# General parameters
######################
# Set the default IP address or hostname Apache JServ binds (or listens) to.
#
# If you have a machine with multiple IP addresses, this address
# will be the one used. If you set the value to localhost, it
# will be resolved to the IP address configured for the locahost
# on your system (generally this is 127.0.0.1). This feature is so
# that one can have multiple instances of Apache JServ listening on
# the same port number, but different IP addresses on the same machine.
# Use bindaddress=* only if you know exactly what you are doing here,
# as it could let JServ wide open to the internet.
# You must understand that JServ has to answer only to Apache, and should not
# be reachable by nobody but mod_jserv. So localhost is usually a
# good option. The second best choice would be an internal network address
# (protected by a firewall) if JServ is running on another machine than Apache.
# Ask your network admin.
# "*" _may_ be used on boxes where some of the clients get connected using
# "localhost"and others using another IP addr.
#
# Syntax: bindaddress=[ipaddress] or [localhost] or [*]
# Default: localhost

# Set the port Apache JServ listens to.

# Indicates the number of idle threads that the pool may contain.

# Indicates the pool controller that should be used to control the

#
# Security parameters
#####################
# Enable/disable the execution of org.apache.jserv.JServ as a servlet.
# This is disabled by default because it may give informations that should
# be restricted.
# Note that the execution of Apache JServ as a servlet is filtered by the web
# server modules by default so that both sides should be enabled to let this
# service work.
# This service is useful for installation and configuration since it gives
# feedback about the exact configurations Apache JServ is using, but it should
# be disabled when both installation and configuration processes are done.
# Syntax: security.selfservlet=[true|false] (boolean)
# Default: false
# WARNING: disable this in a production environment since may give reserved
# information to untrusted users.
security.selfservlet=true
# Set the maximum number of socket connections Apache JServ may handle
# simultaneously. Make sure your operating environment has enough file
# descriptors to allow this number.
# Syntax: security.maxConnections=(int)>1
# Default: 50

# Backlog setting for very fine performance tunning of JServ.
# Unless you are familiar to sockets leave this value commented out.
# security.backlog=5
# List of IP addresses allowed to connect to Apache JServ. This is a first
# security filtering to reject possibly unsecure connections and avoid the
# overhead of connection authentication.
# <warning>
# (please don't use the following one unless you know what you are doing :
# security.allowedAddresses=DISABLED
# allows connections on JServ'port from entire internet.)
# You do need only to allow YOUR Apache to talk to JServ.
# </warning>
#
# Default: 127.0.0.1
# Syntax: security.allowedAddresses=[IP address],[IP Address]... (Comma separated list of IP addresses)
#security.allowedAddresses=127.0.0.1
# Enable/disable connection authentication.
# NOTE: unauthenticated connections are a little faster since authentication
# handshake is not performed at connection creation.
# WARNING: authentication is disabled by default because we believe that
# connection restriction from all IP addresses but localhost reduces your
# time to get Apache JServ to run. If you allow other addresses to connect and
# you don't trust it, you should enable authentication to prevent untrusted
# execution of your servlets. Beware: if authentication is disabled and the
# IP address is allowed, everyone on that machine can execute your servlets!
# Syntax: security.authentication=[true,false] (boolean)
# Default: true

# Authentication secret key.

# Logging parameters
####################
# Enable/disable Apache JServ logging.
# WARNING: logging is a very expensive operation in terms of performance. You
# should reduced the generated log to a minumum or even disable it if fast
# execution is an issue. Note that if all log channels (see below) are
# enabled, the log may become really big since each servlet request may
# generate many Kb of log. Some log channels are mainly for debugging
# purposes and should be disabled in a production environment.
# Syntax: log=[true,false] (boolean)
# Default: true
log=true
# Set the name of the trace/log file. To avoid possible confusion about
# the location of this file, an absolute pathname is recommended.

# jserv.conf file. This is the log file for the Java portion of Apache
# JServ.

# On Unix, this file must have write permissions by the owner of the JVM
# process. In other words, if you are running Apache JServ in manual mode
# and Apache is running as user nobody, then the file must have its
# permissions set so that that user can write to it.

# Syntax: log.dateFormat=(String)
# Default: [dd/MM/yyyy HH:mm:ss:SSS zz]
log.dateFormat=[dd/MM/yyyy HH:mm:ss:SSS zz]
# Since all the messages logged are processed by a thread running with
# minimum priority, it's of vital importance that this thread gets a chance
# to run once in a while. If it doesn't, the log queue overflow occurs,
# usually resulting in the OutOfMemoryError.
#
# To prevent this from happening, two parameters are used: log.queue.maxage
# and log.queue.maxsize. The former defines the maximum time for the logged
# message to stay in the queue, the latter defines maximum number of
# messages in the queue.
#
# If one of those conditions becomes true (age > maxage || size > maxsize),
# the log message stating that fact is generated and the log queue is
# flushed in the separate thread.
#
# If you ever see such a message, either your system doesn't live up to its
# expectations or you have a runaway loop (probably, but not necessarily,
# generating a lot of log messages).
#
# WARNING: Default values are lousy, you probably want to tweak them and
# report the results back to the development team.
# Syntax: log.queue.maxage = [milliseconds]
# Default: 5000
log.queue.maxage = 5000
# Syntax: log.queue.maxsize = [integer]

# Default: false
# Info channel - quite a lot of informational messages
# hopefully you don't need them under normal circumstances
# log.channel.info=true
# Servlets exception, i.e. exception caught during
# servlet.service() processing are monitored here
# you probably want to have this one switched on
log.channel.servletException=true
# JServ exception, caught internally in jserv
# we suggest to leave it on
log.channel.jservException=true
# Warning channel, it catches all the important
# messages that don't cause JServ to stop, leave it on
log.channel.warning=true
# Servlet log
# All messages logged by servlets. Probably you want
# this one to be switched on.
log.channel.servletLog=true
# Critical errors
# Messages produced by critical events causing jserv to stop
log.channel.critical=true
# Debug channel
# Only for internal debugging purposes
# log.channel.debug=true
Any help is greately appreciated.
