Problem or error: The Campaign process creates a zero byte stack or core file.

Solution: The Campaign server (unica_acsvr) uses pstack on Solaris and procstack on AIX to produce a stack trace. The appropriate executable must be in the PATH variable when the Campaign server is started.

On UNIX, the Campaign server always attempts to produce a core file (depending on the cause of the crash), but ulimit settings (configured in the Campaign listener startup script) may restrict its ability to do so. If necessary, you may increase the ulimit setting.
