<p class="MsoPlainText">I’m having trouble setting up the fulltext index on a Debian installation. Admittedly this is a Wheezy installation, not Jessie as we wanted to track a newer version of rt4, so some things may be broken. Hopefully the freeze comes
soon though.<o:p></o:p></p>

<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The “Lost connection to MySQL” error often occurs when a child kills the database connection for the parent, so I’ve tried different permutations of InactiveDestroy in the script itself, for example adding the third line below:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">my $dbh = $RT::Handle->dbh;<o:p></o:p></p>
<p class="MsoPlainText">$dbh->{'RaiseError'} = 1;<o:p></o:p></p>
<p class="MsoPlainText">$dbh->{'PrintError'} = 1;<o:p></o:p></p>
<p class="MsoPlainText">$dbh->{'InactiveDestroy'} = 1; ##THIS LINE ADDED TO SCRIPT##<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But I’m unable to find a magic fix this way. I’ve also tried running the script as the MySQL root user without success.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This appears to be a slightly different issue than what I see in the archives.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Has anyone else seen this or can point me in the right direction to chase down the lost connections?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks!<o:p></o:p></p>
