<TITLE>Channel processing problem with 4.11</TITLE>

<P><FONT SIZE=2 FACE="Arial">Testing in two separate hobbit environments. Both environments are able to process BB-PE traffic. Using Hobbit 4.11 server release and a simple client test file to transmit status to the servers (modified hobbitclient-linux.sh and hobbitclient-hpux.sh).</FONT></P>
<P><FONT SIZE=2 FACE="Arial">First environment using Mandrake 9.0 server and Fedora Core 2 client - client transmissions received and processed properly on server.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Second environment using Fedora Core 3 server and HP-UX 11i client, have problems with hobbitd_channel on server.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Initial error was: Worker process died with exit code 6, terminating</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I reduced down the size of the HP-UX client message - no longer sending ps/top/vmstat output; still blowing up. </FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Commented out some of the signal handler lines and set to ignore some of the signals to drill into problem in the hobbitd_channel.c file.</FONT></P>

<P><FONT SIZE=2 FACE="Arial">Also, has anyone configured hobbit server to work with a number of HPUX clients? Looking to handle around 50 HPUX servers and 50 Windows servers into a single Hobbit server. </FONT></P>
