Troubleshooting
Problem
Intermittently (for example perhaps once a month) Controller Web crashes.
- As a workaround, this is solved by restarting the Windows service "IBM Cognos Controller Web")
During troubleshooting, customer notices errors similar to "Max connections reached 869" in the log file.
