the mysterious shutdown thing

i have been experiencing that too.

but i noticed that the zope process is slowly increasing its memory consumption that my 500MB swap file was turned to zero. i therefore increased the swapfile to 1GB. it hasn't stopped ever since. based on our visitor access, our swap file reached 800MB. oh by the way, our servers have 128MB ram. that could also be it.

we also have the servers in zeo. the main server hasn't stopped running with a 400MB swap file since the client servers with 1GB swap files are the ones taking the load.

good luck!
