the above means the tcl is trying to delete a hash table entry that is not there anymore for some reason you've probably got a malloc arena corruption or double free of some kind happening if i had to make a off the cuff guess. it you have C extensions that would be the first place to look. but it could just be a subtle 7x threading bug.. in which case. you'd have to break out purify or electric fence i know of people having this problem in tcl7.6 when using the rename command under certain situations. > > Does anyone have a good strategy or starting point for debugging this? > Running the server with gdb and waiting for the crash isn't really an > option because I'd have to watch it the whole day, plus once it > breakpoints our production server would be down. > > We're using AS 3.4 and TCL 7x - it's faster than 8x for us, and more > compatible with 2.3.3's TCL. > > Any suggestions are welcome. > Jim
