Hello :)

I have moved this thread over to the Optimization forum. As for the error message, I notice the following path related to the error message:

xcache.mmap_path="/tmp/xcache/"
Have you checked to make sure your /tmp partition is not full, and uses the correct permissions (1777)? EX:
Code:
# df -h
# df -i
# stat /tmp
Thank you.
