Hi,
I am encountering a problem with Reassembly. G_mem_chunk_free is failing. I am
not able to trace the possible reasons. I have written my new dissector which
used reasssembly. The dissector uses a lot memory. Is memory leak cause of this
problem. I am not able to find any possible solutions. THE PROBLEM OCCURS ONLY
DURING REFRESING. :)...
