Hi there,
After some time of running it seems that my process has a lot of
ZEO.cache.Entry objects around... sys.getrefcount reports a huge
number of references (155989 when I only have 625 object references!).
I've run a memory profiler on my code which shows the number of
objects of class ZEO.ca

Hi,
This looks like a bug to me, but maybe I'm just doing something stupid
(possibly it's not allowed to deepcopy a Persistent object and then
re-sync the connection?). Try running several instances of the
following code in parallel (3 is enough for me here). Seems to be some
race condition; I qu
The bug I'm getting on the client side is two or more clients
simultaneously reporting:

Hi,
This issue results in a corrupted database. Can anyone confirm that
they can reproduce this with the test case I provided, so that I can
eliminate any potential problems with my setup as being the cause?
Thanks,

Hi Alan,
Thanks for the advice. I'm using multiple processes, one on each host
in a cluster. The extra thread is only used to run the asyncore loop,
which allows zodb to receive asynchronous notifications. I've been
playing around with your suggestions, and found that if I don't run
the extra asy

claim the filestorage has errors, for example after a single commit
through a zeo server it says:

Thanks for your answers (Alan too). The ZEO server is supposed to
I have a number of processes running on hosts with a common NFS /home.
I was using a file on this shared NFS as a ZODB database. I had
thought that this wouldn't be a problem, since it would be impossible
for any process to open the zodb file while another process has it
locked, but the zodb file k

This might be your problem, you need to use a PersistentDict object if
you want each record to be an individual entry in the database. I

A ZODB client has an in-memory cache in RAM, and an optional on-disk
cache. The server stores lots of objects.
