Seeing the below errors, quite frequently now - didnt do for the first few days the box was up! I have to restart Zimbra to get things working again

Running Zimbra 6.0.8 FOSS 64bit - Ubuntu 10.04 LTS - Anyone any thoughts? Ive tried the zmfixperms extended in case that was anything!

Anyone else seeing this?

Cheers,

iMx
