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

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
