Hi all, This is a zope issue that I think is probably zodb related. I've been seeing this behaviour for a couple of years now. When I inspect /proc/PID/fd (on a linux machine, this lists the open file descriptors held by the process with process id PID), I see many descriptors that point to open files, eg:
$ ls -go /proc/15431/fd | grep deleted lrwx------ 1 64 2009-06-25 10:09 13 -> /var/tmp/tmptBEWCx.tbuf (deleted) lrwx------ 1 64 2009-06-25 10:09 14 -> /var/tmp/tmpKSuzMN (deleted) lrwx------ 1 64 2009-06-25 10:09 6 -> /var/tmp/tmp2HUAnn.tbuf (deleted) lrwx------ 1 64 2009-06-25 10:09 7 -> /var/tmp/tmpex5QmJ (deleted) This gets worse over time until we run out of diskspace, with a trace back like this (somewhat sanitised to protect the guilty): ".../parts/zope2/lib/python/transaction/_manager.py",line 110, in savepoint return self.get().savepoint(optimistic) File ".../parts/zope2/lib/python/transaction/_transaction.py", line 312, in savepoint self._saveAndRaiseCommitishError() # reraises! ".../parts/zope2/lib/python/transaction/_transaction.py", line 422, in _saveAndRaiseCommitishError t, v, tb = self._saveAndGetCommitishError() File ".../parts/zope2/lib/python/transaction/_transaction.py", line 309, in savepoint savepoint = Savepoint(self, optimistic, *self._resources) File ".../parts/zope2/lib/python/transaction/_transaction.py", line 737, in __init__ savepoint = savepoint() ".../parts/zope2/lib/python/ZODB/Connection.py", line 1046, in savepoint self._commit(None) ".../parts/zope2/lib/python/ZODB/Connection.py",line 555, in _commit self._store_objects(ObjectWriter(obj), transaction) ".../parts/zope2/lib/python/ZODB/Connection.py",line 583, in _store_objects s = self._storage.store(oid, serial, p, self._version, transaction) ".../parts/zope2/lib/python/ZODB/Connection.py", line 1180, in store self._file.write(data) IOError: [Errno 28] No space left on device Naturally a restart solves the problem immediately, but this is still a bug. Before I dive into the code and attempt to find the problem, I thought I'd post first, partly to report the problem, but at the same time to find out if anyone has seen this and if perhaps a fix is already available. regards, Izak _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
