Node evictions due to heart beat timeouts with no apparent problem on the IB fabric. Instance evictions due to delayed lms or lmd ping acknowledgements with no apparent interconnect problems. Unexplained delays in java or shell script code on very busy application nodes.
Issues seems to be more prevalent in Solaris 11.2 and 11.3 and is triggered frequently by excessive CPU saturation.
