[Zope] zope 2.4.x crashing on RH 7.x

[bak (kedai)]

hi
setup
tried both zope 2.4.0 and zope2.4.1
data migrated from another zope instance (zope2.3.3) via ChrisM export recipe 
at zopelabs

zope runs ok for a while, but then restars .. and after a while restarts ..
this goes on for a while ..

with big M switch, nothing much on it.   hangs on gif calls, some rdb call, 
some normal dtml method.  

got a few 

 Aiieee! 19489 exited with error code: 11

errors in stupid.log.

a search in the nipltd produced some help, but none that's 
applicable/workable.

but all these runs ok with zope 2.3.3

thanks
