CPU usage spikes when users are joining causing multiple users to disconnect. Most of these users are connecting while on VPN some are not. This also occurs intermittently at different times during times of peak network utilization like at 9:00 AM while users are logging on and during lunch while users are surfing the web. This will cause VPN to drop but reconnect after a few seconds. During the SfB meeting user will have to reconnect. These are all remote users.</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Post.png" style="width: 999px;"><img src="https://community.checkpoint.com/t5/image/serverpage/image-id/5423i1A86E46518532931/image-size/large?v=v2&amp;px=999" role="button" title="Post.png" alt="Post.png" /></span>&nbsp;</P> Mon, 06 Apr 2020 21:43:40 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Multiple-users-drop-during-Skype-for-Business-Call/m-p/81044#M11480 CSD58 2020-04-06T21:43:40Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Multiple-users-drop-during-Skype-for-Business-Call/m-p/81219#M11481 What version of code on what appliance?<BR />What Troubleshooting have you done?
