I noticed this in our hub.log and was curious does this relation..
Jul 6 10:52:55:234  hub: Attempt to build sid exceeding 15021 bytes, greater than maximum permitted length 8192 (may have too many IPs)
I did notice our ssl_session_cache_size is set to 8192 so was wondering any relation should this be bumped up higher if there is relation?
hub 7.95 and earlier
No there is not a relationship between these two.
the SID length is currently hard coded to 8192 in size.
this message can usually be ignored as benign.
