LR 6.4 Windows 7 64bit 24Gb mem no internet connection. All cloud usage disabled, all syncing etc turned off in LR and Creative cloud. Creative cloud itself is suppressed as too intrusive, too many sub tasks I have no use for.
LR set with blank grid view and totally idle.
Monitoring Task Manager LR is creating a Thread every 8 seconds with 100k mem working set used up.
These threads persist. Left running over lunch had reached 530 threads and mem usage up by over 100Mb.
If connect to internet thread count stabilises but existing threads do not die.
Appears a background thread is created to access the internet which does not abort on failing to connect.
Totally unacceptable behaviour, when idle LR should be doing nothing whatsoever and certainly should not be constantly accessing the internet.
Certainly expect to be able to use LR with no internet connection.
