I have never used 7.0.2 for any length of time....but I would recommend
upgrading to 7.1 - many bugs have been fixed in this release - and hopefully
not too many more introduced :)

also adding more RAM would be a good idea, as 64Mb is not much these days ( I
use apache 1.3.19 + mod perl 1.25 and regularly see 150Mb RSS when I run gtop
)

This may be a Red Herring, but check to see you are not exhausing your swap
space, as all sorts of odd errors can be encouraged by this...

Cheers
