Thanks, Chris. We're fronting two Zopes with Pound for load balancing. I can't see there would be any connection with this error. But I mention it in case there's a pattern. Also, the database came from 2.7.0 and an earlier python. This looks like resource starvation to me. The servers run for an hour or two this problems shows up, becoming worse for a while, then we need a restart. I'm try to debug it tomorrow. What would you look for? Any tips for resource monitoring? --r. On 22 Jul 2004, at 21:49, Chris McDonough wrote:
I have seen this as well but I haven't been able to pin it down.

Hi all,
On OSX 10.3 (Pahter), Python 2.3.4, Zope 2.7.1, I'm frequently seeingthis.. 2004-07-22T14:00:24 ERROR(200) ZODB Couldn't load state for00000000000016ad Traceback (most recent call last): File "/usr/local/zope/zope271/lib/python/ZODB/Connection.py", line559, in setstate p, serial = self._storage.load(oid, self._version) File "/usr/local/zope/zope271/lib/python/ZEO/ClientStorage.py", line755, in load self._cache.store(oid, p, s, v, pv, sv) File "/usr/local/zope/zope271/lib/python/ZEO/ClientCache.py", line601, in store self._store(oid, p, s, version, pv, sv) File "/usr/local/zope/zope271/lib/python/ZEO/ClientCache.py", line631, in _store f.seek(self._pos) AttributeError: 'NoneType' object has no attribute 'seek'
It's intermittent at first, then back-to-back.
Following thread leads me to look for memory shortage. But I'd expecta different message in that case. http://www.mail-archive.com/zope-dev@zope.org/msg15039.html
This thread seems to suggest such messages (in different context) canbe ignored. But I can't do that. This is a symptom of a bigger problem. http://mail.zope.org/pipermail/zope/2001-August/097300.html
Has anyone seen this in these circumstances? --r.
