As you know that, SS fails to handle the HUGE REST query when it receives from OC Server and also generates a big core file while processing that huge REST query.
In 393a patch, we have restricted the number of nodes which are present in REST search query to avoid the SS crash.
It's always good to prepare optimal search query instead of giving all IP addresses in the search list.
Kindly suggest customer to use "By IP Address Range" filter or giving less number of IPs with "By IP Address" filter to process the query.
Symptom: SpectroSERVER Crashes when huge REST query receives from OneClick server.
Resolution: SpectroSERVER does not Crashes and shows an Error.SearchQueryCombinationsExceedStackProcessingSize error to OneClick server when huge REST query receives.
