Are you running the RedHat kernel?

If so, check out:

There have been many reports on the PowerEdge list of trouble with the
tg3 driver in various RedHat kernels. To date, it seems that the tg3
driver in the stock Linus kernels does not cause the hang, though
there may be some other bugs, especially wrt IPv6. Specifically,
there are serious incompatibilities with Apache when running IPv6:

Sounds like the tg3 bug people have been complaining of.

As above, it seems it is OK to do so if you are NOT running a RedHat
kernel and you are NOT using IPv6.

The PowerEdge list is a good one. A couple of Dell and RedHat hackers
hang out there, and although I run Debian exclusively, if you want
info about your particular hardware, it's a good place to check.
