![]() ![]() Suspected Root cause: It's still under investigation but if this is correct it seems to be a problem introduced by a change in the winstation driver wdica.sys Using this way I can consistently bring out the problem within 5-30 seconds. Then start clicking with your mouse on the empty desktop until the problem happens. The easiest way to force and bring out the problem is therefore to start a continuous copy of a very large file inside the Citrix session on the from the MAC client machine towards the VDA or remote network inside the VDA. The problem only happens when inside the Citrix session from the MAC a client-redirected device or drive is being accessed or used in any way. This particular problem was introduced as early as of VDA agent 2112 and is present in all later editions. The issue will not happen with a Windows CWA The CWA client must be a MAC (or potentially other non-windows). So you won't see the problem when connected through a third party VPN or internal network. The problem only happens when the connection is happening through a Netscaler Gateway. ![]() After all this troubleshooting I have have identified that: So, Citrix engineers, is there something going on here with Mac OS?īREAKING NEWS everyone on the specific issue of MAC (and possible other non-windows) CWA clients getting randomly disconnected unexpectedly with the " connection interrupted" pop-up message: After months of troubleshooting with both the Netscaler engineering team and VDA engineering team I just finished testing a new special build with a private fix in it that seems to solve the problem completely. I don't have any kernel panic or app crash. It's not very elegant, but it works for me. I use multiple monitors (3) for my work and if I drag my cursor to the bottom of the screen on a monitor that does NOT have the dock on it, and thus move the dock per MacOS, the Citrix instance windows reappear! It is my workaround so that I don't have to quit Citrix and relaunch multiple times daily. A right click on the Citrix Viewer icon in the MacOS dock shows progress, progress, progress indicating that the 3 instances are still live, but one or more of them is no longer visible. One or more will randomly disappear, but not actually quit. I have noticed a pattern that suggests that there is a conflict of some sort between the MacOS "Dock" and Citrix because of the following.Įxample: I'll have 3 Citrix instances running for my application. Multiple monitors makes it even worse and frequent. My device is an iMac (Retina 5K, 27-inch, 2020.) Intel Core i5 CPU, 32GB RAM. I have a similar if not same issue using Citrix Viewer v.22.01.0.25 (2204) launch mode ICA and MacOS 12.4, although it has been present since at least MacOS 11.x (BIg Sur). VM - pmap_enter failed with resource shortage ![]() Termination Reason: Namespace SIGNAL, Code 4 Illegal instruction: 4īUG IN CLIENT OF LIBDISPATCH: Release of a locked queue Path: /Library/Application Support/Citrix Receiver/Citrix Viewer.app/Contents/MacOS/Citrix Viewer When I go to "About this Mac", I can see the serial number. Then when I disconnect, I get the following crash report.Īdditional information: this problem persists in versions 2206. In this case, the screen remains frozen after I reconnect, the windows don't move. Sometimes I am able to continue work, sometimes not. In order to reconnect, I have to open a new window. The disconnects are NOT network interruptions with a 5-minute timeout, but the desktop window simply disappears. I keep getting multiple disconnects with my remote desktop per day. I am using Citrix Workspace for MacOS version 2206. I own a MacBook Pro (14-inch, 2021) with M1 Pro chip. ![]()
