Other than kernel updates, nothing specific. They have varied from SCSI 
tape drivers becoming hung, to issues with services crashing and not 
being able to be restarted, or getting hung. 

The kernel updates thing does bring me to another issue, in that with 
these comes the possibility of third-party support. One issue that was 
painful was when a customer (with good intentions) ran a software 
update, which updated the kernel, and on reboot the EMC SAN wouldn't 
mount. After spending hours on the phone it was determined that EMC did 
not yet have a version that worked with the particular kernel version 
included with the update, and that it would probably be a month or so 
until they did. 

Admittedly, there don't seem to any common issues with these servers, 
however we have enough in the field doing things unique to each one that 
we can make the comparison. The end-use for both the Sun & the RHEL 
boxen are generally the same, however we receive far fewer support calls 
on the Solaris servers than we do on the RHEL servers. 
Thanks,
