Sunil,
Can I configure this heartbeat to use a high priority (realtime)
schedulling?
If I simply increase the timeout it still could timeout on heavy I/O
situations, like several different threads queuing large amounts of writes. The
kernel should know this is a high priority write so that it is put ahead of the
queue.
Regards,
Luis
