I can't explain the "cache5p" other than it could be a memory
corruption bug.

If your cache is not able to keep up with the load, you might want
to set the 'max_open_disk_fds' option in squid.conf. This will
limit the number of disk files that get opened for writing. Setting
this limit will decrease your response times, but it will also
decrease your hit ratio.
