The string length of the absolute path for the directory mount point for the archive directory address must be less than 124 characters. If an archive path is 124 characters or longer, a database exception similar to the following is created:

  3. MySQL: DataError: (1406, “Data too long for column ‘details’)

Archiving Status: Target File Write Stalled (Linux)

Starting in exacqVision 6.6, the Archiving page can report a status of Failed – Target File Write Stalled. This status is displayed after 15 minutes of inactivity during an active archive task. While in this condition, archiving is stalled and hardware monitoring is stopped, but video recording continues normally. This condition affects only Linux-based exacqVision systems.


To recover from this condition, restart the system. Because the stall is related to the Linux kernel, the system restart could also stall, and the system must be power cycled manually by unplugging and plugging in the power cables. (If the server has a capture board with watchdog enabled, the watchdog will be triggered during the system restart.).


After the system is restarted, follow these instructions to disable cifs caching and prevent additional archiving stall conditions.
