During rush hours when multiple users access U2000 client, some functions freeze and U2000 client becomes unresponsive.
Check the resources U2000 requires per user:
Checking the actual environment installation for U2000 found out the following:
1) The disk space is 32G
2) All the 3 U2000 domains were deployed ( IP,Access,Transmission) and disk space is not enough for all the 3 domains
Insufficient disk space.
Considering the fact that actual U2000 is managing only Transmission devices, if Access and IP domains will be undeployed, the issue is solved.
