Version 5.8.1 [V5-stable] (rgerhards), 2011-05-19

• bugfix: invalid processing in QUEUE_FULL condition
  If the the multi-submit interface was used and a QUEUE_FULL condition
  occured, the failed message was properly destructed. However, the
  rest of the input batch, if it existed, was not processed. So this
  lead to potential loss of messages and a memory leak. The potential
  loss of messages was IMHO minor, because they would have been dropped
  in most cases due to the queue remaining full, but very few lucky ones
  from the batch may have made it. Anyhow, this has now been changed so
  that the rest of the batch is properly tried to be enqueued and, if
  not possible, destructed.

• new module mmsnmptrapd, a sample message modification module
  This can be useful to reformat snmptrapd messages and also serves as
  a sample for how to write message modification modules using the
  output module interface. Note that we introduced this new
  functionality directly into the stable release, as it does not
  modify the core and as such cannot have any side-effects if it is
  not used (and thus the risk is solely on users requiring that
  functionality).

• bugfix: rate-limiting inside imuxsock did not work 100% correct
  reason was that a global config variable was invalidly accessed where a
  listener variable should have been used.
  Also performance-improved the case when rate limiting is turned off (this
  is a very unintrusive change, thus done directly to the stable version).

• bugfix: $myhostname not available in RainerScript (and no error message)

• bugfix: memory and file descriptor leak in stream processing
  Leaks could occur under some circumstances if the file stream handler
  errored out during the open call. Among others, this could cause very
  big memory leaks if there were a problem with unreadable disk queue
  files. In regard to the memory leak, this

• bugfix: doc for impstats had wrong config statements
  also, config statements were named a bit inconsistent, resolved that
  problem by introducing an alias and only documenting the consistent
  statements
  Thanks to Marcin for bringing up this problem.

• bugfix: IPv6-address could not be specified in omrelp
  this was due to improper parsing of “:”
  closes: http://bugzilla.adiscon.com/show_bug.cgi?id=250

• bugfix: TCP connection invalidly aborted when messages needed to be
  discarded (due to QUEUE_FULL or similar problem)

• bugfix: $LocalHostName was not honored under all circumstances
  closes: http://bugzilla.adiscon.com/show_bug.cgi?id=258

• bugfix(minor): improper template function call in syslogd.c
