Very soon after we made some changes to our OneClick Users structure, the OneClick server crashed, out of memory with a hprof file.
Why did this happen and what can we do to prevent this from happening again in the future?
Too many users were connected into OneClick when the changes were made, causing OneClick to use up additional memory which was required to update all active users.
Release : 10.4.x
Component : Spectrum OneClick
Problem was caused by making a change to User Groups while many users were connected which caused OneClick Server to send an update to all OneClick clients.
Engineering suggests that any changes done to the users should be done after hours or when less users are connected to prevent this from happening again.
