Bad idea. Now even a one second delay will cause a disconnect. Under
load, it's entirely possible to have a 1 second delay reconnecting
due to open fds, locks, etc. That delay will cause the client to
drop the connection. Then it will reconnect, have the same delay,
and drop the connection.<br>
<br>
Why is 42 seconds too long? Is your network so bad that you lose
connection so often that a more stable cluster is a bad thing?<br>

That just seems impractical with regard to cpu and network usage. I
would much rather have my servers servicing client requests than
spending all their time spinning to see if an absent server has
returned.<br>
<br>
It seems that it checks every 3 seconds now to see if it's returned.
That goes back to my previous statement. If your network is so
unstable that 3 seconds to start self-heal is excessive, perhaps you
might look at a more stable network.<br>
<br>
That said, feel free to open an enhancement request on bugzilla to
allow the user to tune the reconnect interval.<br>
