it's possible this is (inadvertently) an Oracle Trace problem as Oracle Trace is enabled by default from 7.3.2 on in Unix

Metalink note 45482.1 has information on how to disable it (see below). I've seen this happen in just this way.

Workaround A - No Oracle Trace output required:

Shut down all databases and listeners.
Remove the Oracle Trace files:

	  Unix				    NT 
	  ~~~~				    ~~ 
          cd $ORACLE_HOME/otrace/admin	    cd orant\otrace73\admin 
          rm -f *.dat	    	    	    del *.dat 
      					    Reboot the NT server

Workaround B - Disable Oracle Trace on specific connections

NB: This workaround is not applicable to NT.

Shutdown and remove the trace configuration files as in Workaround A.
Reinitialise the Oracle Trace files by typing 'otrccref' in the otrace/admin directory.
To disable Oracle Trace for a particular session set the environment variable EPC_DISABLED to TRUE. Eg: In a Bourne script: EPC_DISABLED=TRUE; export EPC_DISABLED

             In the C-Shell: 
                setenv EPC_DISABLED TRUE 
 
      4. To set EPC_DISABLED=TRUE for SQL*Net connections you can
modify  
	 the 'SID_LIST_listener' clause in the 'listener.ora' file and add: 
 


                (ENVS='EPC_DISABLED=TRUE') 

 
         to the SID_DESC for each 7.3 database. Add the entry AFTER the

         (ORACLE_HOME=...) clause. 
 
         Eg: 
            SID_LIST_LISTENER= 
             (SID_LIST= 
              (SID_DESC= 


                (SID_NAME=DB1) 

                (ORACLE_HOME=/oracle/OFA_base/app/oracle/product/7.3.2)




                (ENVS='EPC_DISABLED=TRUE') 

              ) 
              (SID_DESC= 


                (SID_NAME=DB2) 

                (ORACLE_HOME=/oracle/OFA_base/app/oracle/product/7.3.2)




                (ENVS='EPC_DISABLED=TRUE') 

              ) 
            ) 
 
	   By using two listener processes you can have one SQL*Net alias 
	   which allows tracing and another that has tracing disabled. 
 
        5. Restart and databases and SQL*Net listeners.
