The MaxWait preference can be set to 12000 in the "RiSystem" guru object (ri.sys.ObjectClass = ri.sys.RiSystem) to avoid TCP connection time-outs when the Guru server is far away or on a high latency network environment (ping > 100ms). Self generated GuruIDs that end in a "XA" will get a RiSystem object automatically created when if firsts connects to a Guru Server. This may fix situations where the time needed to transfer the object exceeds the default MaxWait time.
