I installed the update with no perceptible errors, but now I have a new error:
Verbose error follows:
an end-of-file was reached
An end of file occurred
I believe we've had this error before. When we upgraded the machine our
gridftp server is running to an Opteron running a 64-bit kernel, we had
problems running our gridftp client accessing other sites due to (I
didn't investigate this myself, but was told) an end-of-file error.
globus-url-copy seemed to access other sites' data fine.
Now however, where globus-url-copy accessed data fine through our server
on the 64-bit machine (minus the group membership bug), it does not anymore
and responds with the above error.
Note that all binaries are of the 32-bit flavors.
Do you know anything about this issue? I'm guessing I may have more luck if I
have 64-bit binaries of the globus tools, but haven't had the chance to test
Cheers & Thanks,
