deferring operation: pending operations

["Ben Beuchler" <insyte@gmail.com>]

I'm getting a ton of these errors in a row, all on the same connection:

Apr  5 11:32:48 swizzle slapd[1626]: connection_input: conn=6232680
deferring operation: pending operations
Apr  5 11:32:51 swizzle slapd[1626]: connection_input: conn=6232680
deferring operation: pending operations
Apr  5 11:32:51 swizzle slapd[1626]: connection_input: conn=6232680
deferring operation: pending operations
Apr  5 11:32:52 swizzle slapd[1626]: connection_input: conn=6232680
deferring operation: pending operations

What does "deferring operation: pending operations" actually indicate?

Thanks!
