Dear all, we are running veraPDF as a validation service in our system for thesis submission. Lately we encountered a problem on server where Vera instances run. In some cases, Vera is not able to produce output (because of timeout or something), so the script that called Vera instance finishes validation process and the validated file is deleted from the temp directory. Usually, it does not cause any problems, but sometimes Vera does not finish (?why?) and still runs and blocks the server and needs to be killed manually. In these situation, the Vera instances block fully the server and it rises problems for other applications running on the server too. We do not know if it is caused by fact that Vera still runs and needs the validated file that was already deleted. We do not know how to solve the problem and prevent to blocking the server with unfinished Vera instances. Has anyone experienced a same problem?
