Netware 4.11 and time.

Is there any possible way that changing the Netware time back 6 minutes would cause a replica to go into hung state or become corrupt?

I recently change the time back on one of our servers, "synthetic time" messages started to appear but went away in about 10 minutes. All seemed Ok, until about 1 hour later, R/W replica on one server just went out lunch. i has to use DSRepair -xk2 to remove it.

thanks!
