What user are you logged into the OS as before starting the terminal/csession?<PROTECT> errors can sometimes be caused by OS-level permissions on the CACHE.DAT. I recommend to make sure this user has permissions on the CACHE.DAT file and directory. It could be working through SMP because that process will run as the same user as other background processes, which could be a different user than your terminal process. 3 0 https://community.intersystems.com/post/protect-error#comment-33116 go to post Lisa Moak · Nov 3, 2016 Hi Mikhail, Please also see Kate's answer regarding the cuxagent process. It's possible that the cuxagent just isn't logging anything at the time.Is there a particular problem you are seeing that you are trying to diagnose with this logging? 1 0 https://community.intersystems.com/post/iscagent-debug#comment-17731 Certifications & Credly badges:Lisa has no Certifications & Credly badges yet.Global Masters badges:Lisa has no Global Masters badges yet.Followers:Lisa has no followers yet.Following:Lisa has not followed anybody yet.
