TypeError im ZCatalog

Hallo allerseits,

ich habe mit collective.catalogcache experimentiert.

Die Ergebnisse waren hervorragend (Performancesteigerung nach
Warmlaufphase zwischen 300% und 500% je Seitentyp).

Nach einigen Stunden intensiver Nutzung stellten sich aber Fehler ein,
die mit der Zeit häufiger und letztlich quasi zum Regelfall wurden:

Ich bin mir bewusst, dass collective.catalogcache nur "experimental"
ist, aber ich würde gern verstehen was dort passiert.
collective.catalogcache greift bei Fehlern oder Cachefehlzugriffen auf
die normalen ZCatalog-Routinen zurück und genau hier scheint das Problem
aufzutreten.

Viele Grüße
