You were probably hit a bug described in this upstream article:

https://access.redhat.com/solutions/1302043

Check to see if the tg3 version is 3.137 (modinfo tg3). If so, one
workaround is to downgrade the tg3 driver.  Luckily, ELRepo's kmod-tg3
for EL6 is at 3.136. Install the kmod and see if this resolves the
issue.
