The maximum number of storage errors to tolerate before stopping the gather.
Can be set in: collection.cfg
This option is effective with TRIMPush data sources only. It specifies how many consecutive storage errors will be tolerated before the update is stopped. A storage error might occur if the target push collection has a problem.
This is to prevent the crawl from continuing without storing anything if the target push data source enters a permanent error state, but at the same time account for possible temporary errors.
