Since you have gone so far to research the cause, do you have a recommended solution? If so, please submit a pull request to <a href="https://github.com/DOCGroup/ACE_TAO" class="">https://github.com/DOCGroup/ACE_TAO</a></div><div class=""><br class=""></div><div class="">Given the apparent urgency of your request, I suggest you investigate commercial support. Take a look at <a href="http://www.cs.wustl.edu/~schmidt/commercial-support.html" class="">http://www.cs.wustl.edu/~schmidt/commercial-support.html</a> for a list of vendors.</div><div class=""><br class=""></div><div class="">Finally, I suggest you create a bug report in bugzilla: <a href="http://bugzilla.dre.vanderbilt.edu/" class="">http://bugzilla.dre.vanderbilt.edu/</a></div><div class=""><br class=""></div><div class="">It would be helpful if you can prepare a runnable test that demonstrates the problem and submit that with your pull request and / or the bugzilla entry. Take a look at any of the ACE/tests as an example. Also, be sure to say what platforms are affected, windows, linux, etc.</div><div class=""><br class=""></div><div class="">The bugzilla entry is particularly important if you are unable to provide a fix or fund the development of one. In that case, it may take a while for someone to come up with an acceptable solution gratis.</div><div class=""><br class=""></div><div class="">Best Regards,</div><div class="">Phil</div><div class=""><br class=""></div><div class=""><div><blockquote type="cite" class=""><div class="">On Nov 28, 2016, at 2:12 AM, Jack Wong <<a href="mailto:pandawkx@163.com" class="">pandawkx@163.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="line-height: 1.7; font-size: 14px; font-family: Arial;" class=""><div class=""><span style="font-family: arial; white-space: pre-wrap; widows: 1;" class="">ACE VERSION: 6.3.0</span></div><div class="">(this bug still exists in version 6.4.0)</div><div class=""><br class=""></div><div class="">Our test codes looks like this:</div><div class=""><br class=""></div><div class="">1:while (true)</div><div class="">2:{</div><div class="">3: reactor()->purge_pending_notifications(xxx);</div><div class="">4: reactor()->notify(xxx);</div><div class="">5:}</div><div class=""><br class=""></div><div class="">after a while , we found dead-lock occurs at line 4.</div><div class=""><br class=""></div><div class="">－－－－－－－－－－－－－－－－－－－－－－－－－</div><div class=""><br class=""></div><div class="">I check the code and found that :</div><div class=""><br class=""></div><div class="">purge_pending_notifications can only purge message in notify queue</div><div class=""><br class=""></div><div class="">messages in pipe can not be purged</div><div class=""><br class=""></div><div class="">so calling notify() after purge_pending_notifications() can always leads one message be write to pipe</div><div class=""><br class=""></div><div class="">So when I keep calling like this , soon buffer of pipe will full and notify() will be blocked , then dead-lock occurs</div><div class=""><br class=""></div><div class="">－－－－－－－－－－－－－－－－－－－－－－－－－</div><div class=""><br class=""></div><div class="">we are using this two interfaces building important functions of our application</div><div class=""><br class=""></div><div class="">we will appreciate it if this bug being fixed soon</div><div class=""><br class=""></div><div class="">－－－－－－－－－－－－－－－－－－－－－－－－－</div><div class=""><br class=""></div><div class="">poor English, sorry!</div></div><br class=""><br class=""><span title="neteasefooter" class=""><div class=""> <br class="webkit-block-placeholder"></div></span>_______________________________________________<br class="">ace-bugs mailing list<br class=""><a href="mailto:ace-bugs@list.isis.vanderbilt.edu" class="">ace-bugs@list.isis.vanderbilt.edu</a><br class="">http://list.isis.vanderbilt.edu/cgi-bin/mailman/listinfo/ace-bugs</div></blockquote></div><br class=""><div class="">
