<DIV>Hi,</DIV>
<DIV>Now, I am getting the traces from gcMalloc and finishGC by simply printing out the "bsz" and "GCBLOCKSIZE(info)"<BR>values. But the trace patterns still same for different java programs. Is this normal or am I missing something?</DIV>
<DIV> </DIV>
<DIV>Thanks for the help,<BR>Suat<BR><BR><B><I>Helmer Krämer <hkraemer@freenet.de></I></B> wrote:</DIV>
