These SIGSEGV signal messages have been determined to be sent from debugging code that was not disabled. Note that all Mac users of CS4 applications, or Acrobat/Reader 9.0 would see these messages in their system.log, so any crashes are merely coincidental. However, if your crashes are related to a problem with the FLEXnet licensing server, this solution may also fix that, as it causes many of it's files to be refreshed, which could remove corruption.
