The message "C++ Exception: bad allocation" typically indicates that one of the processes being accessed on Tableau Server has reached the upper memory limit available to the process. This is usually caused when running Tableau Server in a 32-bit environment or with versions prior to 7.0.4, which have a limit of 2 Gigabytes of accessible memory. With 7.0.6 on a 64-bit machine that limit has been increased to 4 Gigabytes.
To diagnose this type of message please take the following steps:
1. If Tableau Server is not on the latest version I recommend upgrading to 7.0.8 to take advantage of the memory improvements, which will help avoid this message. I have included upgrade instructions below.
2. Break up workbooks that contain many dashboards and worksheets into multiple workbooks if possible. Additionally, if your dashboards contain many complex worksheets, you may wish to lessen the number of worksheets per dashboard.
3. Prevent competition for hardware resources by turning off any other applications running on the Tableau Server machine.
