Environment


System Configuration: sun4v Sun Fire T200 running Solaris 10
vxfs (VxFS 6.0 SunOS 5.10)
vxlo (Veritas Loopback Driver 0.1)

Cause


A variable being protected by mutex lock "vxlo_ctl_lock" was accessed before the lock was properly released by the vxlo module of the VERITAS File System product.

Solution


There is a hot fix (HF) for Sparc servers based on SFHA 6.0 Rolling Patch 1. (6.0RP1HF1)

Symptoms
