Subject: Bus errors & segfaults

I've been getting daily Bus Errors on various ruby classes, which is
crashing our Mongrel server pretty much every day.

Here is an example error:

ruby(15833,0xa000ed88) malloc: *** error for object 0x41b20d0: pointer
being reallocated was not allocated
ruby(15833,0xa000ed88) malloc: *** set a breakpoint in szone_error to
debug
ruby(15833,0xa000ed88) malloc: *** error for object 0x41b20d0: pointer
being reallocated was not allocated
ruby(15833,0xa000ed88) malloc: *** set a breakpoint in szone_error to
debug
/usr/local/lib/ruby/1.8/pathname.rb:266: [BUG] Bus Error


Here is another one I get:

ruby(805,0xa000ed88) malloc: *** error for object 0x308ff20: pointer
being reallocated was not allocated
ruby(805,0xa000ed88) malloc: *** set a breakpoint in szone_error to
debug
ruby(805,0xa000ed88) malloc: *** error for object 0x308ff20: incorrect
checksum for freed object - object was probably modified after being
freed, break at szone_error to debug
ruby(805,0xa000ed88) malloc: *** set a breakpoint in szone_error to
debug
ruby(805,0xa000ed88) malloc: *** error for object 0x308ff20: pointer
being reallocated was not allocated
ruby(805,0xa000ed88) malloc: *** set a breakpoint in szone_error to
debug
/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action_controller/rescue.rb:136:
[BUG] Segmentation fault

It's running on OS X Server 10.4.8.  2GB RAM.

Any ideas?
