Please see abort_prob setting of an agent (robot or server):
http://www.web-polygraph.org/docs/reference/pgl/types.html#type:docs/reference/pgl/types/Agent
PolyMix and WebAxe workloads use that feature. If you test with
abort_prob enabled, you may want to check response times for aborted
transactions. Some proxies have inexcusably long (minutes) delays
associated with them.
Finally, you can also simulate dropped connections on a packet level
with DummyNet- or NISTnet-like tools. PolYmix workloads simulate
packet loss that way.
