Matthew - I performed the operations that you recommended and here are the results (see below). The problem seems to be with the value of the tp_traverse field. I am not aware of any "T" type python object. I'm wondering if this is an extension class type (just a guess). I searched through all of the *.c files in zope, etc. but I as not able to find any type of name "T". I also ran across a bug posting at sourceforge ... http://sourceforge.net/tracker/?func=detail&atid=105470&aid=471942&group_id=5470 This bug report looks very similiar. - j #0 0xef5b9810 in _lwp_sema_wait () (gdb) info threads 19 Thread 10 0xef5b9810 in _lwp_sema_wait () 18 Thread 9 0xef5b9810 in _lwp_sema_wait () 17 Thread 8 0xef5b9810 in _lwp_sema_wait () 16 Thread 7 (LWP 8) subtract_refs (containers=0x13dec8) at ./Modules/gcmodule.c:166 15 Thread 6 0xef647cac in _swtch () 14 Thread 5 0xef5b9810 in _lwp_sema_wait () 13 Thread 4 (LWP 0) 0xef647b7c in _swtch () 12 Thread 3 0xef647cac in _swtch () 11 Thread 2 (LWP 2) 0xef5b9958 in _signotifywait () 10 Thread 1 (LWP 6) 0xef5b7488 in _poll () 9 LWP 9 0xef5b6a24 in door_restart () 8 LWP 8 subtract_refs (containers=0x13dec8) at ./Modules/gcmodule.c:166 7 LWP 7 0xef5b9810 in _lwp_sema_wait () 6 LWP 6 0xef5b7488 in _poll () 5 LWP 5 0xef5b9814 in _lwp_sema_wait () 4 LWP 4 0xef5b9810 in _lwp_sema_wait () 3 LWP 3 0xef5b9810 in _lwp_sema_wait () 2 LWP 2 0xef5b9958 in _signotifywait () * 1 LWP 1 0xef5b9810 in _lwp_sema_wait () (gdb) thread 16 [Switching to Thread 7 (LWP 8)] #0 subtract_refs (containers=0x13dec8) at ./Modules/gcmodule.c:166 ./Modules/gcmodule.c:166: No such file or directory.
