        2     CEEPGTFN    +00000064              CEEPLPKA
    ...

        14
    Java_com_ibm_etools_zos_server_CoreJNI_checkFileSystemUsage
    
    RDz operator command Display Process will show the process with
    a timeout

    01.When file systems for user log files are getting full and
       existing log files are truncated, abend 0c4 sometimes
       occurs.
    
       A CEEDUMP may show a traceback like:
    
       1 conditionHandler 2 CEEPGTFN +00000064 CEEPLPKA
    
       10 IBMZOS_GetStringPlatformLength 11 GetStringPlatformLength

       ProcessId(50332110) Memory Usage(21%) Clients(10) Order(28)
       *timeout*
    

Problem conclusion

  • 01.Not to close the file pointer that causes intermittent
       abends, the host module is updated to call ftruncate()
       without removing the files and to change the timing to
       restart the subsequent log output.
