lib10jox.a file locked error while applying patch 10.2.0.4

  Hi,
we are trying to patch our 10.2.0.2 database on AIX 5.3 with 10.2.0.4
During the installation, we keep getting error about a file $ORACLE_HOME/lib/libjox10.a being locked and unable to copy

using the fuser command we found that the only process using that file is actually is the process running the Installer (/patch/Disk1/Installer)

# fuser -c /u01/10gR2/lib/libjox10.a
/u01/10gR2/lib/libjox10.a:   942310c 1175610 1196194c

ps -ef|grep 1175610
