Review Comment:
I think two log messages for one event is an anti-pattern of sorts.
Can we simply log the exception message and the exception here? the log appender format will determine if the stacktrace is spit out in the log

Review Comment:
nit: I think the log should say _why_ it is discarding -- temp space full or temp space disabled.
