Are there any service packs or patches for ZLM7?

We had a working mirror of SLES9, which would patch our sles9 servers via
rug up, but it suddenly stopped working. For new patches, rug up will
download the patches to the sles9 server's local cache from the ZLM server,
and then at the point where it should be installing the patches, it hangs
forever until you kill the rug process ID.

At Brinashare one of the engineers told me that there was a patch for ZLM7
that fixes this problem, but I can't find a ZLM update channel anywhere nor
can I find any ZLM7 patches on There is also no documentation
in the ZLM manual about how to keep ZLM itself updated.

Can anyone help me?
