[Zope] Zope 2.7 threws many exceptions and dies

[Michael Heidel]

Hi list,


we run Zope 2.7.2 final (Python 2.3) on an OpenBSD 3.5 box (P IV 2.4 
GHz, 1 GB RAM), started by zopectl.

Zope will die up to several times a day. Most times Zope will restart 
after a while, sometimes it doesn't.

Sometimes event.log would show some hundreds of entries per second like

-- snip --
2004-09-01T13:19:52 PROBLEM(100) ZServer warning: server accept() threw 
an exception
-- /snip --

before zope dies.

Also we find Cache exceptions - event.log shows:

-- snip --
2004-09-01T11:26:50 PROBLEM(100) Cache ZCache_set() exception
Traceback (most recent call last):
   File "/usr/local/lib/zope/lib/python/OFS/Cache.py", line 215, in 
ZCacheable_set
     mtime_func)
   File 
"/usr/local/lib/zope/lib/python/Products/StandardCacheManagers/RAMCacheMa
nager.py", line 317, in ZCache_set
     oc.setEntry(lastmod, index, data, view_name)
   File 
"/usr/local/lib/zope/lib/python/Products/StandardCacheManagers/RAMCacheMa
nager.py", line 111, in setEntry
     self.entries[index] = CacheEntry(index, data, view_name)
   File 
"/usr/local/lib/zope/lib/python/Products/StandardCacheManagers/RAMCacheMa
nager.py", line 57, in __init__
     raise CacheException('The data for the cache is not pickleable.')
CacheException: The data for the cache is not pickleable.
-- /snip --


Physical RAM is o.k.



TIA,

Michael
