ERROR: clEnqueueReadBuffer() -5

[phrst]

When running oclHashcat on a nvidia gtx260 on ubuntu 64bit i get this error:

Code:

ERROR: clEnqueueReadBuffer() -5

It usually happens after 30 seconds to a minute and after this error the cracking speed drops to 0.

This is the command I'm running:

Code:

oclHashcat64.bin -n 8 -o /tmp/outhash /tmp/hashes ?l?l?l?l ?l?l?l?l

Does anyone have a possible solution for this?
