Kernel panic: Fatal exception




Oracle DBAs are using the following script which results in a kernel
panic when run from cron.  Seems to work from command line.

#!/bin/sh
ORACLE_HOME=/oracle/product/9.2.0; export ORACLE_HOME
LD_LIBRARY_PATH=$ORACLE_HOME/lib; export LD_LIBRARY_PATH
TNS_LOG=$ORACLE_HOME/network/log; export TNS_LOG
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
PATH=$ORACLE_HOME/bin:.:$PATH; export PATH

stopprocs() {
  lsnrctl set log_status off
  agentctl stop
}

startprocs() {
  agentctl start
  lsnrctl set log_status on
}

listenerlog() {
  LOG=listener.log
  cd $TNS_LOG
  test -f $LOG.2 && mv $LOG.2 $LOG.3
  test -f $LOG.1 && mv $LOG.1 $LOG.2
  test -f $LOG.0 && mv $LOG.0 $LOG.1
  mv $LOG $LOG.0
}
