Let’s assume it’s not hardware, Dennis has posted the tests and states

The fact that Solaris runs fine can be an indicator the hardware is okay, but
it's not a proper verification that it's actually the case.
For example, if one of the memory modules is bad, it could happen that the error
shows on Linux but not on Solaris because both allocate different memory regions
right after the machine has started.
So, if, for example, you want to verify that the memory is okay, you should run
a memtest program.
...the built-in (memory) diagnostics of Sun machines are pretty
thorough. This is not a PC. :-)
