Resolution:
The RTserver is reporting that it received a signal from the OS that a file size limit has been exceeded. This is likely to be a log file that the RTserver is creating. You can use  "ulimit -a" to check  the file size limit on your system, and then compare that to the file sizes of your log files by using "ls -l" in the directory where your log files are written.

If your RTserver trace file is very large then you should consider reducing the trace_level you are using or rotating logs when they reach a certain size.  Trace_level values above Info_1 are only recommended during times of active debugging of a problem, and should only be enabled at the recommendation of TIBCO Support.  If you are logging messages into and/or out of the RTserver we recommend that you disable this logging unless you are actively debugging a problem and have been instructed to perform logging by TIBCO Support.
