Problem with barracuda backup.

Hi everyone

I have a virtual barracuda backup machine (firmware version 6.5.01.10081). Once a week I backup for tapes using barracuda export tool (firmware version 1.1.02.70039). For the last month I have a problem with ending backup in barracuda export tool "Error 5165: PHP command submodule encountered a fatal error" (screenshot).

Someone has a similar problem ?

Regards Adam
