Hello! I wonder what to do when zope coredumps? I have been given the advice to hook up gdb to zope/python and see what happens, but there are two problems with this: 1) I barely know gdb at all, let alone know how to hook it up to a running process 2) The dumps happen at random (last one happened at 3 in the morning when a co-worker was working from home). I only have core dumps to work from. I include the stack from latest core dump. I am using python 2.1.2 (release), Zope2.4.3 release, RedHat Linux 7.2. Python is compiled --without-pymalloc What can I do more to track this down? Thanks, /dario ----- #0 0x0806fb77 in subtract_refs (containers=0x80b228c) at ./Modules/gcmodule.c:170 #1 0x0806ff74 in collect (young=0x80b228c, old=0x80b2298) at ./Modules/gcmodule.c:382 #2 0x080701c2 in collect_generations () at ./Modules/gcmodule.c:479 #3 0x08070255 in _PyGC_Insert (op=0x8c1dbbc) at ./Modules/gcmodule.c:508 #4 0x0807eb8e in PyMethod_New (func=0x82fa3dc, self=0x8c1d50c, class=0x82f9f14) at Objects/classobject.c:1834 #5 0x0807c74c in instance_getattr2 (inst=0x8c1d50c, name=0x8168e00) at Objects/classobject.c:642 #6 0x0807c67e in instance_getattr1 (inst=0x8c1d50c, name=0x8168e00) at Objects/classobject.c:608 #7 0x0807c789 in instance_getattr (inst=0x8c1d50c, name=0x8168e00) at Objects/classobject.c:656 #8 0x0808d291 in PyObject_GetAttr (v=0x8c1d50c, name=0x8168e00) at Objects/object.c:1052 #9 0x0809b7ba in builtin_hasattr (self=0x0, args=0x8d8cb94) at Python/bltinmodule.c:886 #10 0x08058df1 in call_cfunction (func=0x80c79c8, arg=0x8d8cb94, kw=0x0) at Python/ceval.c:2850 #11 0x080577ac in eval_code2 (co=0x82d91a0, globals=0x82ebd9c, locals=0x0, args=0x8a3a7e0, argcount=1, kws=0x0, kwcount=0, defs=0x0, defcount=0, closure=0x0) at Python/ceval.c:1952 #12 0x080590a3 in call_eval_code2 (func=0x82f9fb4, arg=0x8a3a7d4, kw=0x0) at Python/ceval.c:2971 #13 0x08058ce4 in call_object (func=0x82f9fb4, arg=0x8a3a7d4, kw=0x0) at Python/ceval.c:2810 #14 0x08058f77 in call_method (func=0x82f9fb4, arg=0x80cb8fc, kw=0x0) at Python/ceval.c:2928 #15 0x08058cd1 in call_object (func=0x8b9f2dc, arg=0x80cb8fc, kw=0x0) at Python/ceval.c:2808 #16 0x08058bcb in PyEval_CallObjectWithKeywords (func=0x8b9f2dc, arg=0x80cb8fc, kw=0x0) at Python/ceval.c:2745 #17 0x0807c433 in PyInstance_New (klass=0x82f9f14, arg=0x80cb8fc, kw=0x0) at Objects/classobject.c:489 ------ - -------------------------------------------------------------------- Dario Lopez-Kästen Systems Developer Chalmers Univ. of Technology dario@ita.chalmers.se ICQ will yield no hits IT Systems & Services
