[9.171][BUG] Fallback log Can't access file /tmp/ctasd.cache - fopen failed

Hi I'm seeing on boot
2013:11:30-15:18:43 fmaster [local0:err] ctasd[5598]:  CEnginesContainer::LoadCache() - [00001000Q0066K138E1S] Can't access file /tmp/ctasd.cache - fopen failed (2)
2013:11:30-15:18:43 fmaster [local0:info] ctasd[5598]:  Load cache finished

Is this normal?
