Hi Comunity,

I have been in troubles with Zope2.10.5-final since 4 moths ago,
related to the "MemoryError: out of memory" (in the event.log), every
three or fourth days (more or less) the Zope starts to say in our web:
value error: Memory, and stops to serve some pages (not all), usually
the pages that serve file contents (to download, convert to pdf or
view online). I solve the problem (when appears) by rebooting the zope
server, but its not a solutions, because I dont know when the error
its coming ¿Can you help me to giving me some light to solve the
problem? I have 2gb of RAM, and the server (FreeBSD) it says
no-overloaded, just have 2 services, web(zope) and database(mysql). I
think its something related to the cache memory or kind of (I changed
some values in config file but not success). See some of my event.log

Traceback (innermost last):
