Hi I have IDL 8.1. I have some problems with License Manager. In order to run the IDL, first I have to run ./lmgrd (~/Applications/itt/idl/idl81/bin/lmgrd). Then I can run the IDL. But it goes disconnected randomly (sometime after 30 minutes sometimes after shorter time). This is the error that I get: (idl_lmgrd) Lost communications with lmgrd. (idl_lmgrd) EXITING DUE TO SIGNAL 37 Exit reason 5 % LICENSE MANAGER: No server response after 3 attempts (3:0 minutes). Does anybody know how to fix this?
