7 years ago This looks like a crash in the image loader from the log you posted on the forums. The core dump won't be useful because it's for the whole JVM and I've never been able to get anything good out of those. The best way to resolve this is to see if it can be reproducible, I'd expect to see the same image being referenced in the log file when this crash happens. So if you can figure out what that is, then it should be easy to reproduce and fix.

Recently I had several core dumps when viewing the Parallel Schedule page.

(See thread starting at https://forums.sagetv.com/ forums/showthread.php?p=606550&postcount=332). I had upgraded to v9 several weeks ago but hadn't noticed the problem until yesterday, so it may be related to the v9 upgrade (from v7).
Currently I am running 9.1.4 on linux x86_64 with Java 1.8.0_131. In all three cases where this occurred, I was scrolling around the parallel recording schedule listing while something was being recorded. Then the UI hung and shortly after the process crashed. This was on FiOS recording from HDHomeRun Prime tuner using my prime_encoder script (https://github.com/ jwittkoski/prime_encoder) which has been pretty stable for several years.
I have a core file from the crash that occurred shortly after the initial hang. It's 1.5G in size so is there some information can I include from the core dump to help debug? Traceback? jstack dump?
