How to recognize transient failures: they usually affect only one single job (disk or DB failures), or a small number of jobs all on the same machine (LFS failure). If a process complains about a missing file but the file exists, or gets a read error after opening a file, it's probably a disk server hiccup. If the log file ends suddenly, without the usual LSF postlog, the batch host probably crashed. There will probably be several jobs failing the same way at the same time.
What to do in case of transient failures: rollback the affected process(es) when possible (see below for the rollback procedure). Look for the dontCleanUp file and check the Log Watcher (see below). If recon segfaults for no apparent reason, email Heather and Anders before the rollback, including a link to the log file, which will tell them where the core file is.

How to recognize infrastructure failures: they usually affect a large number of jobs, either on the same LSF host or on different LSF hosts.
What to do in case of infrastructure failures: these failures involve a large number of people to be taken care of (the infrastructure expert on-call and often also the SCCS), so for the time being still page Warren and/or Maria Elena (see L1 shift schedule) if you think that one of those failures might be happening during the night (if in doubt, page anyways).
...
How to recognize permanent failures: besides those 2 cases, everything that doesn't get fixed after a rollback is by definition a permanent failure.
What to do in case of permanent failures: contact the appropriate people above, if you are sure you know what happened. Otherwise, page Warren and/or Maria Elena (see L1 shift schedule). If there is another part of the run waiting, the run lock (see below) will have to be removed by hand; page unless you're really sure of what you're doing.
