What are the causes of a corrupted database?

Answer

webx.db is the Web Crossing Database file. This file is nearly always being updated. Interrupting Web Crossing without a proper graceful shutdown can corrupt the database.

For example, but not limited to:


  • Power Failure.
  • Hardware problems...most typically flakey disk drives, sometimes bad memory modules..same as with any software.
  • Forcing Web Crossing to shut down improperly (kill -9 rather than make-quit).
  • Web Crossing dies due to other system process(es) crashing and taking WebX with them.
  • A reboot without prior proper WebX shutdown (assuming your system doesn't try to shut webx down normally by default).
  • Multiple instances of WebX attempting to access the same database.
  • Insufficient available sytem memory or disk space or heavy virtual memory "thrashing".
  • Extremely low cache settings for a large and/or very active database ("Memory Usage").
  • Restoring webx.db directly from a system backup and not via Web Crossing generated backup files (webxdb.NN and webxroll.NN).
