Unica Campaign server creates a zero byte stack or core file
Problem or error: The Unica Campaign process creates a zero byte stack or core file.
Solution: The Unica 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 Unica Campaign server is started.
On UNIX, the Unica Campaign server always attempts to produce a core file (depending on the cause of the crash), but ulimit settings (configured in the Unica Campaign listener startup script) may restrict its ability to do so. If necessary, you may increase the ulimit setting.
