-----------------------------------
Summary: The dd2spring generated Spring files accumulate in the
temp dir
Key: UIMA-2753
URL: https://issues.apache.org/jira/browse/UIMA-2753
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
On UIMA-AS process startup, the provided deployment descriptors are passed
through the dd2spring which generates a Spring context file used to initialize
the UIMA-AS service. Once the initialization is done the context files can be
removed. The dd2spring actually creates the context files as temp files and
configures the files with removeOnExit(). In most cases this works, however
when the UIMA-AS service is killed with -9, the temp files remain in the
default temp dir accumulating over time. The DUCC runtime frequently kills the
services to make room for another process so these files temp files do in fact
accumulate in the temp dir.
It seems like the agent should spin a thread, check temp dir for old temp files
and clean them up. The cleanup would have to be done via ducc_ling as the files
are owned by users.
