[App_rpt-users] e/l un-authorized

my node seems to have stopped accepting echo link connects - giving the un -authorized message, no matter how long the e/l station as been logged onto the network The message that appears on the console is: [Oct 18 12:51:24] ERROR[2620]: chan_echolink.c:2185 do_new_call: Cannot find DB entry for a/ipaddr/77.43.22.231 I note that astdb is about 17.4 MB in size - is this reasonable? If not, is there a way to shrink/reset safely? Ken
