<font face="sans-serif">Hi, There,</font>
<br>
<br><font face="sans-serif">I am using omniORB 4.1.4 with my project.</font>
<br><font face="sans-serif">Recently, when I testing with SLES,
I noticed that, the server side hit memory corruption some time (not always).</font>
<br>
<br><font face="sans-serif">With ORBtraceLevel set to 45, I got
following trace information:</font>

<br><font face="sans-serif">What I noticed are:</font>
<br><font face="sans-serif">1. The memory corruption problem not
happened all the time, and when problem happened, generally the 2nd try
will pass.</font>
<br><font face="sans-serif">2. All corruptions happened to me so
far were related to relative big data (about 24K), and it happened related
to "inputCopyChunk" as trace shown above.</font>
<br><font face="sans-serif">3. The size server side got is correct,
even the content got corrupted. (The size 24432 bytes is correct in the
example I copied here)</font>
<br><font face="Courier New">omniORB: (7) inputCopyChunk: from giop:tcp:[::ffff:10.6.25.60]:56354
24432 bytes</font>
<br><font face="sans-serif">4. When corruption happened, sometimes
the content just got truncated, sometimes the contents just replaced by
some meaningless contents at the end.</font>
<br>
<br><font face="sans-serif">Please help me.</font>
<br><font face="sans-serif">Thanks.</font>
