This condition may be caused by a number of different conditions. A temporary disruption of network service may cause replies to be delayed past the timeout period. Timeout periods that are too small may cause fanout processing to abandon polling for replies before a reasonable amount of time has passed. Excessive administrative traffic may be clogging the network causing undue delays. If the condition occurs infrequently and is not attributable to a particular request, then no action is indicated. If the condition occurs consistently after a particular request, then examine requests made just previously to see if their timeout values are too small. If the condition occurs frequently, then the T_DOMAIN timer attribute values (TA_SCANUNIT, TA_BBLQUERY, TA_BLOCKTIME, TA_DBBLWAIT and TA_SANITYSCAN) may need to be raised to reduce administrative traffic on the network. Additionally, the administrative tools being used to monitor the system may need to be examined to identify excessive traffic they may be injecting into the system.
