FlexHub has default settings for '!set security SR' that are too tight.
Innocent users can be disconnected for flooding searchresults, when a few quick passive searches are made by (an)other user(s).
Advised to use the following settings:
!set sr_useraction1 Ignore
!set sr_usermax1 20
!set sr_usertime1 10
This will ignore searchresults if there are more than 20 in 10 seconds
!set sr_useraction2 Disconnect
!set sr_usermax2 200
!set sr_usertime2 20
This will disconnect the user if he sends more than 200 in 20 seconds.
