We use wirehark on a heavy-load environment (we have the /3Gb switch set in the
boot.ini file to use the maximum amount of memory):

With Wirehark Version 99.6 we can do a trace until the known bug "out of
memory" appears. The memory-usage in the task-manager grows straight
proportional (s. also the picture 99_6_normal_behavior.jpg in the attachment).

Since Version 99.7 & 99.8pre1 we are not able to trace for a longer time.
We have always the fault message "Glib_ERROR **:gmem.c:172:failed to
allocate..". The memory usage grows non-linear (=> see also the picture
99_8_pre1_bug.jpg in the attachment).

Is it possible to correct this in the new versions ?

Thanks & Best Regards
Ernst
