No clue - for some reason the call stack is corrupted, so you can't see where traceEvent() is being called from (nor, for that matter the text of the fields).
All I can think of is ugly. Put a gdb trap on 1996 (i.e. the line it's dying on), and then for each one do a "info stack; cont" -- that way when it dies, you should have the info before it was corrupted. Note that you may have to put the trap earlier (maybe 1945, i.e. the 1st line in traceEvent(), if it's say the memset that's corrupting things. -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Steven Rudolph Sent: Friday, November 14, 2003 12:18 PM To: [EMAIL PROTECTED] Subject: [Ntop] Solaris 8 Segmentation Fault 1.
