To follow up, I found another user on the system with a core file from a crash and here is the (not terribly informative) backtrace from the crashed nxagent process:

#0  0x080ebe61 in XauReadAuth ()
#1  0x0809d814 in XauReadAuth ()
#2  0x0809d083 in XauReadAuth ()
#3  0x080a48ea in XauReadAuth ()
#4  0x0807ddeb in ?? ()
#5  0x00000000 in ?? ()

The platform is Scientific Linux 4.2 with ROOT 5.12.00a on AMD64 and NX server 2.0.0.
