Hello,
my Zope 2.9.8 instance crashes up to 6 times per hour. This is very unfortunate since the constant restarting brings performance to its knees.
It runs under Linux in 64 bit mode on an AMD64 . I managed to catch two backtraces with gdb (see end of the mail). Both backtraces show a crash in cc_oid_unreferenced(ccobject *self, PyObject *oid) in persistent/cPickleCache.c: Either in line 576: v = PyDict_GetItem(self->data, oid); or in line 607: Py_DECREF((ccobject *)((cPersistentObject *)v)->cache);
v and v->cache seem to point to heap: (gdb) print v $1 = (PyObject *) 0x5f8920 (gdb) print ((cPersistentObject *)v)->cache $2 = (PerCache *) 0x613620
Always called from Per_dealloc(cPersistentObject *self) in persistent/cPersistence.c in line 578: cPersistenceCAPI->percachedel(self->cache, self->oid);
Is this a known issue?
Thank you for any help,
Can you reproduce using the following from-scratch build? $ cd /tmp $ wget http://www.zope.org/Products/Zope/2.9.8/Zope-2.9.8-final.tgz $ tar xzf Zope-2.9.8-final.tgz $ cd Zope-2.9.8-final $ ./configure --with-python=/path/to/64-bin-python \ --prefix=/tmp/z298 && make && make install $ /tmp/z298/bin/mkzopeinstance.py -d /tmp/instance -u admin:123 $ /tmp/instance/bin/zopectl fg Tres. - -- =================================================================== Tres Seaver +1 540-429-0999 tseaver@palladion.com Palladion Software "Excellence by Design" http://palladion.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHsIMr+gerLs4ltQ4RAlPbAJ95lNWC8M0qBkN9zS3zfdqRTtvSRACfSQj+ KzySBx/+qsJnYTmMX3UPEAM= =b509 -----END PGP SIGNATURE-----
