Troubleshooting Method
Files are accumulating on
chassis
 Make sure that there is no high network latency between L-ESS and chassis.
 Make sure that file generation rate is not too high on chassis.
 Check if L-ESS is loosing connections repeatedly.
 Check if CPU consumption of L-ESS is higher than expected.
 Check if SSH Daemon on chassis is busier than expected.
 Check if any other application residing on L-ESS is causing heavy system resource
consumption.
 Make sure that L-ESS processes are running in FSS scheduler if L-ESS is started with
priority based solution. This can be tested by using ps -cafe command. For
example, all below processes are running under FSS scheduler.
#ps -cafe | grep ess
