# The deadman timer is typically used to detect if an I/O is hung.
# On object store pools, the deadman timer check for a hung socket
# connections between the kernel and the agent. Reducing this
# to 1 minute will allow the kernel to detect this condition quickly
# and restart the agent if the connection is hung.
