ACE doesn't general SIGUSR2, so I suspect you're running into issues
with your OS platform, which is probably Linux.  To ensure that we
have proper version/platform/compiler information, please make sure
you fill out the appropriate problem report form (PRF), which is in


or in


in older versions of ACE+TAO.  Make sure to include this information
when asking any questions about ACE+TAO since otherwise we have to
"guess" what version/platform/compiler/options you've using, which is
very error-prone and slows down our responsiveness.  If you don't use
the PRF, therefore, it is less likely that someone from the core
ACE+TAO developer team will be able to answer your question.
Naturally, we encourage and appreciate other members of the ACE+TAO
user community who can respond to questions that they have the answers

BTW, please upgrade to ACE+TAO+CIAO x.5.10 (i.e., ACE 5.5.10, TAO
1.5.10, and CIAO 0.5.10), 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
