All RDF Reports Running Forever With No Completion

Problem: I face one internal issue that in production instance , concurrent program are running from long time and are not getting completed.

Symptoms:

 All RDF reports like "ACTIVE USER" are running forever with no completion and no error in request/manager/internal manager log.

Submit Active Users with command line: CONCSUB

CONCSUB is a utility to submit the concurrent request from operating system level to run concurrent program, without having to log on to oracle applications.

$CONCSUB apps/<pass> SYSADMIN "System Administrator" SYSADMIN WAIT=Y CONCURRENT FND FNDSCURS PROGRAM_NAME='"Active Users"'

OR

$INST_TOP/ora/10.1.2/bin/appsrwrun.sh userid=apps/apps mode=character report=$FND_TOP/reports/US/FNDSCURS.rdf batch=yes destype=file desname=./ddr2.out desformat=$FND_TOP/reports/HPL pagesize=132x66 traceopts=trace_all tracefile=ddr2.trc tracemode=trace_replace
