I noticed in my event.log that I’m getting tons of these messages:

2004-09-28T04:50:17 PROBLEM(100) Cache ZCache_set()

exception

Traceback (most recent call last):

    mtime_func)

    self.entries[index] = CacheEntry(index, data,

line 57, in __init__

    raise CacheException('The data for the cache is

not pickleable.')

CacheException: The data for the cache is not

pickleable.

Can anybody give me any advice on how to track down this kind of message?  I don’t see anything in here that hints at what particular object is causing this error or why.  What I’m wondering is whether this is an issue where I put something into a cache that shouldn’t be there or perhaps that something got corrupted somewhere.

Another thing I noticed (probably as a result of this) is that the memory consumed by the process grows constantly.

Finally, I’m using Zope-2.7.0 because of http://zope.org/Collectors/Zope/1401 in Zope-2.7.2 in case anybody is wondering why I’m not using the latest Zope.

Any help would be appreciated.  I tried Googling but it only turned up three matches for that exception and none of them helped me.
