Environment

Issue



SCSP may cause a crash in Solaris 9 or Solaris 10 systems when NFS shares are heavily accessed by remote NFS clients. The crash is caused when the IPS driver dereferences a NULL pointer to a vnode cache entry that is used to monitor NFS server activity.  


Environment



This defect applies to any environment in which the Solaris 9 or Solaris 10 bundled NFS server software is used directly or indirectly (e.g., when loaded by Veritas Cluster Server NFSAgent).

Affected operating systems: Solaris 9 and Solaris 10 with high NFS Server activity

Affected Symantec Critical System Protection versions:
  • Solaris 9: Release 5.2.8 MP3 or earlier.
  • Solaris 10: Release 5.2.8 MP4 or earlier.

Solution



Solaris 9: Resolved in 5.2.8 MP4

Solaris 10: Will be addressed in the SCSP 5.2.9 release.

Current Workaround: Disable Intrusion Prevention [IPS]
