Eric: Thanks for your response. I have upgraded the kernel to 2.6.19, and have exactly the same result: I get a segmentation fault immediately after invoking jconsole. Other 64-bit applications seem to work correctly, so I think it may be J-specific. The 32-bit version runs fine in compatibility mode, including jw if I ensure that 32-bit Java gets called. I have the 64-bit libj601.so in the lib64 directory. My suspicion is that the the 32-bit library is being found by accident, or that there is some environment variable problem: I doubt it is a general incompatibility question. If anyone has installed the 64-bit Linux version on Intel x86_64 (not AMD64), especially on Fedora Core or other Red Hat distributions, I would appreciate any tips.
