Intermittent issue with MAXL script to enable connects on ASO cube

***We are using Essbase 11.1.2 on premise. We rebuild an ASO cube every night. We use maxl script as automation. The last command in the total process is to enable connects on the cube. Sometimes the process does not respond after the command as it does with previous commands. Here is the log from the script.
