Bug 749023

Well, "easily" is debatable since it is Axis2/C that manages the log file. It appears we would have to write our own logging extensions to achieve log appending, etc. There is still logging that occurs in the lower layers that we don't control.

Modified code to collapse to single file logging from Aviary schedd plugin and Query Server respectively. There is still no "sync" point save timestamps between Condor and the Axis2/C logs generated.

    accordingly. All revisions will be proofread by the Engineering Content Services team.

Cause: Previous version of Aviary generated many per-pid log files from the Axis2/C engine.
Consequence: Unnecessary proliferation of files in logging directory.
Change: Aviary logging setup now makes use of a single log file each for the Aviary schedd plugin and the query server that is continually appended to across process restarts.
Result: Aviary Axis2/C log file count dramatically reduced.
