Maybe off-topic, but it definitely related to nsunix...
I get this error message frequently in my server log when my OACS instance keeps running:
Error: nsunix: DrvSendFd unexpectedly, write returned -1!errno is 32 (Broken pipe) at fileoffset 55024 with towrite 6761784
Notice: dbdrv: opening database 'postgres:localhost::video'
What does it mean?
