It might be, but the 283 patch has fixed the random crashes I've been
experiencing, which relate to a free() of memory in the fork() child.

Burton,

  Right (I think maybe I'm confussing the issues.) I see no problems with
the pbuf.c patch that you made.
The machine I've installed it on has not crashed with any warnings about
pbuf.c.
It has however died with this backtrace....

 ntop[26039]: CLEANUP: ntop caught signal 11
 ntop[26039]: **ERROR** BACKTRACE: *****ntop error: Signal(11)
 ntop[26039]: **ERROR** BACKTRACE:     backtrace is:

Which seems to be the same problem that was posted in PR_YKDZ9WX....
So I went hunting for a possible bug in glibc and found that PR 5031, which
I thought could very well be casing these problems.
 (Random crashes of ntop under heavy load) But I'm not really sure so I
thought I'd pass it along....
