Hi All,
I upgraded to 1.14 last week and within a few days I started to see some
pretty odd behavior, I'm hoping someone has either seen it before or could
point me to a deeper level of troubleshooting.
Here are the symptoms I observed.
* Performance issues:
Processor performance very poor. Even simple processors like router and
updateattribute went from being able to process 100,000recs/min to
100recs/min or stop all together, but not consistently.
Processors needing to be force killed, even simple ones like
updateattribute.
* Weirdness. One of my routers lost its mind and didn't recognize the
routes configured anymore. It changed all the arrows to dotted lines except
for the default. I ended up copying it and replacing it with the copy, no
changes mind you, but it worked fine.
* Errors: I have not found any obvious errors in the nifi logs that could
explain this, but one error keeps repeating in the logs: SQLServerDriver is
not found . I have dozens of processors that use SQL Server, all seem to be
working fine. This is not tied to a particular processor's configuration. I
don't think this is related.
* Server resources fine. I use htop and sar to troubleshoot hardware issues
usually, all looks normal. I added 1/3 more memory to the JVM, now at 24GB,
just for good measure, but that had no effect.
Is it possible there are some hidden performance issues going on within the
JVM I need a special tool to see?
Any help would be greatly appreciated.
Thanks,
Scott
