Troubleshooting the StateBuilder process

If the StateBuilder process (installationDirectory/pw/server/bin/statbld) fails to start, try the following solutions:

  • Check the installationDirectory/pw/server/var/cellName directory for the number of xact.n files, where n is 1, 2, 3, and so on. The presence of more than three xact.n files indicates that the StateBuilder process is failing. If more than three xact.nfiles are present, follow these steps:
    1. Check the installationDirectory/pw/server/var/cellNamedirectory to see if either of the following files is present:
      • mcdb.0
      • mcdb.lock
    2. If either of the files is present, delete them.

  • From a command line, manually run the StateBuilder process by entering: statbld -n cellName
    • Check the installationDirectory/pw/server/var/cellName directory to ensure that xact.n  xact.1, xact.2, and so forth exist. If the file does not have the numeric extension (.n) (the file is named only xact with no extension), then rename the file to xact.1.
    • Determine whether or not the installationDirectory/pw/server/bin/statbld program exists and can be executed by the current user who is running the mcell process.
    • Verify the available memory for your system and compare it with the actual memory usage of the mcell process.
      On some UNIX and Linux platforms, available unused virtual memory must equal or exceed the virtual memory used by the mcell process.
