rogerskat_private, We have tested 108653-41 and confirmed that it does prevent overflow. Note that SPARC lbxproxy is not set(anything - uid/gid). We will update eSO-3761 accordingly. Thank you for the information.

Is there any stronger evidence that these patches fix this problem, and not some unrelated issue with lbxproxy? Has anyone been able to reproduce the original issue, as well as verifying that the patch fixes it? - rogerskat_private >From: "Charles M.
