The only pattern I see is that it starts all of a sudden, goes for

I'm not sure what a "run-time symbol table" is, and if it gets
rebuilt at any time, or is something thats part of the program, or what....
But its not like one time it behaves one way, then another time it behaves
another.
My description would be hazy at best, so hopefully someone more au fait
will chime in. But I can definitively state that, no it isn't something
that gets rebuilt every so often.
However, if you run ktrace on a simple program like ls: ktrace ls
then do a kdump | less, you will see that after finding ls,
/libexec/ld-elf.so.1 is the first thing accessed. So, when things start
working again, /libexec/ld-elf.so.1 is magically fixed, which just makes
no sense.
I assume there are no other messages obvious errors in /var/log/messages?
One final thought is that it could be the disk. You could try
installing smartmontools and see if the disk thinks it is OK -- though
of course it could be the controller. But in such a case I might expect
other errors.
I'd think if it was a memory issue, it'd be something other than
the same "Shared object..." thing each time. One time it'd be a bus error,
another time a "this isn't executable", etc....
The classic bad memory symptoms are periodic reboots, and random
segmentation faults. The latter is particular to bad memory, I would
say. The fomer can have other causes.
It's the intermittent nature of the fault that really makes me think
hardware. Am I right in remembering that you upgraded to 5.4 and still
had the same problems?
