[ZODB-Dev] Zeo cache files : how to estimate the space?

[Dominique Arnoult]

Hello,
i deal with a problem of /tmp. I have a 1 Go partition and cannot easily
change it. I run a Zeo cluster of 7 clients. Since the lsof command, I can
see 7 process and each process has 4 files opened of 100 Mb max. That
corresponds of the cache-size directive of my zopecore.conf. But, I don't
undertstand why there are 4 files and not only one by zeo client. Any can
help me?
