Hello Navi,
Few details of LSS i have shared as below. Moeover I have not experienced this issue but one of my friend has faced such issue and as per him
this should not be any problem with config but some loose wiring/dut on connector/any in some curcumstances power level of equipment
But i did not find any document who support this statement. Anyway you can go ahead as stated in above statement as a last try

5.3.3 Out-of-service defect information
An out-of-service defect occurs when there is a change of state of the test signal from its normal state. Since some
out-of-service test equipment uses PRBSs which are embedded in standardized path signals, it might also be possible to
evaluate in-service defects (see 5.2.3).
NOTE ā Some test equipment which uses a PRBS that is not embedded in a standardized path signal can experience a
condition which is referred to as āLoss of Sequence Synchronizationā.
Loss of sequence synchronization can occur as a consequence of:
ā long duration intense error burst;
ā long duration AIS;
ā uncontrolled bit slip;
ā loss of signal.
The criterion to declare āloss of sequence synchronizationā is manufacturer-specific and can be highly variable between
different manufacturers. The standardized criterion for loss of sequence synchronization in test equipment is given in the
O-Series Recommendations.
5.3.4 ES and SES evaluation from out-of-service anomaly and defect information in test equipment
