No more available App Servers

When our app servers max out, "No More Available App Servers," it was told by support that we could locate the culprit by identifying the PID generated in very large DBI files.

Will any of these files provide any evidence on what is causing our system to "crash?"

The support staff for our software that uses Progress suggested taking the PID from the end of the largest DBI files and cross referencing with the log files to identify the PID. I've done this, but the PID ends up being associated with many of the users using the MRP software.

Last resort. Can somebody recommend a consultant that could identify the underlying cause of our crashes? The MRP company thinks it's in one of the customized queries we run.
