Hi Michael,

   Thanks for using the PRF.

>VERSION 1.4       VERSION 1.5
>ACE: 5.4a_p4      ACE: 5.5.4
>TAO: 1.4aPp4      TAO: 1.5.4

Please upgrade to ACE+TAO+CIAO x.5.9 (i.e., ACE 5.5.9, TAO 1.5.9, and
CIAO 0.5.9), which you can download from


under the heading: "Latest Beta Kit".

The DOC groups at Washington University, UC Irvine, and Vanderbilt
University only provide "best effort" support for non-sponsors for the
latest release, as described in


Thus, if you need more "predictable" help for earlier versions of
ACE+TAO, I recommend that you check out


for a list of companies that will provide you with ACE+TAO commercial



>HOST/TARGET MACHINE: Linux (RedHat AS3 - but same issue on AS4)
>COMPILER: gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-52)
>I have created a simple program that outputs various ACE_DEBUG levels
>(TRACE,DEBUG.INFO.NOTICE,ERROR).  I also have a svc.conf file that
>disables a few so they will not appear in the output:
>dynamic Logger Service_Object * ACE:_make_ACE_Logging_Strategy()
>One version is written to use just ACE (-d for debug and -f name
>for svc.conf use) and the other with TAO (-ORBDebug for debug and
>-ORBSvcConf for svc.conf).  I print out one group of debug messages,
>perform a ACE_Service_Config::reconfigure(), and then another group
>of debug messages.
>The ACE version that uses the ACE_Service_Config::open behaves
>as expected in both versions (even though there is an Logger
>re-inititalize warning in the 1.5 version) in that is outputs
>only the DEBUG, WARNING, and ERROR statements.  The valid output
>occurs before and after the reconfigure.
>The issues:
>(1) In both versions (1.4/1.5) of the TAO test code, the svc.conf
>    "appears" to load properly at startup, but the first set of debug
>    messages include all messages types, as if the sync.conf file
>    or the priorities are ignored.
>(2) With the 1.4 version of the TAO test code, the proper debug
>    messages are outputted only after the ::reconfigure() is called.
>    This does not occur in the 1.5 version.  In fact, there is no
>    way of disabling any priorities, every log level is outputted.
>(3) I do not know if this is part of the problem with the 1.5 but
>    when performing the reconfigure function, the ACE::debug output
>    shows the following "warning":
>    ACE (13041|3076387488) SG::initialize - repo=0x8790468,
>       Logger is already initialized. Remove before re-initializing
>    This is the same output seen with the ACE test code.  I could not
>    find a way to remove the dynamic services before calling
>    reconfigure.
>Our current project is using the ACE/TAO 1.5, but the log files are
>being overwhelmed with all debug levels.  Any help would be greatly
