We have multiple jobs that run every 15 minutes all day long. They almost always work correctly within VisualCron. However, every so often one of the jobs will not finish and eventually time-out (22 hours later). This happens even if it is processing no data on a simple copy function. The only thing I can see that may be common is that these jobs use IP Addresses to access files for parsing and copying. (Note: these are .bat and .cmd jobs submitted through an execute command.)
Also note that these jobs have run for years using Windows task scheduler and have never had a time-out issue once. Now that they run on VisualCron, we get at least one hanging every day.
Is it possible that VisualCron is losing connection to these jobs and never is notified that it completes? This does, of course, keep the job from being resummitted so we go for hours without data being processed. (No, we cannot run it more than once concurrently).
