Hi,
Based on what I read, my guess is that it’s potentially something about the way the temp files are generated/named… there have been various issues in the past that have been fixed in Java with symptoms like this, and then I’ve found other discussions from the particular library vendor talking about them fixing issues, maybe something regressed in Java 7 or 8?
Anyhow, in reading around, one possible cause is if the new temp file name clashes with an existing file. This is supposed to be unlikely, since the files are generated with random numbers. But if this problem is so reproducible for you, maybe we can help narrow down when & why it’s happening.
When you get the error, try the following:
- Stop the Ignition service.
- Go to C:\windows\temp and delete all of the folders that start with “jniwrap-*”.
- Start again, see if the error occurs. Try restarting a few times if you want.
If it keeps happening after this, or happens after a short period, maybe we can look at other causes.
Regards,
