I'm using bfgminer 3.2.0 and at no set time (4 days the first time, about 22 hours the 2nd time) all found blocks are rejected until I restart mining. Is anyone else having this issue?

Is there a way of monitoring it so I can set a script to restart the mining if the 'rejects' appear? Should I set a scheduled task to restart mining every hour?

Post all the flags/arguments you're running BFGMiner if it happens again.

sounds to me like you're mining scrypt on a bitcoin pool or mining bitcoin on a scrypt pool.

You can use CGWatcher to restart the miner if accepted shares stop increasing for X minutes, along with several other monitoring and scheduling options.

https://bitcointalk.org/index.php?topic=185553.200

Nobody can say for certain what is causing your problem unless you post more info (specifically your config file or arguments, you can remove the username/password if you wish). Is it possible you have both a scrypt pool and a sha256 pool set in the config? (or vice versa?) Then something is causing the first pool to go down and when it switches to the backup the rejects start.

Do the rejects stop at a certain point or go on indefinitely? or have you not waited around long enough to find out? (which I don't blame you, but may be helpful in identifying what is going wrong).

You mean found shares not blocks? The found shares might be all rejected when you have a fast miner and pool decides to lower your difficulty to 1 for some reason.  If you have networking issues, they might become stales and be rejected.

You can monitor rejected shares by making an API call.  Monitor if your rejects increase above certain threshold and restart the miner.
But this will not solve your underlying problem.  It is probably one of the three things: your network issues, your worker/pool configuration and your miner configuration that can cause this.

Pool should not be rejecting all shares.

He means, what is the time set in your operating system?  When you send shares back to your pool, it goes back with a time stamp on them. If the time stamp doesnt match up, it gets rejected.  Many times with people saying that all their shares are being rejected, its because the time on their OS is not set correctly (few hours off, few years, wrong month, etc).

Squiggly letters, written really fast, with a couple of dots for good measure.
