We have application deployed on tomcat & its working good for most of the customer, but recently we installed it for two customers on a virtual machine & it looks like tomcat is crashing after few days.
Machine Details:
It is a Virtual Machine
Both the server crashed with almost exact same crash log.

=====================================
From my research on Google & if I am reading this crash logs correctly it seems to me like the tomcat crashed on "org.apache.tomcat.jni.Poll.poll" class when used from "org.apache.tomcat.util.net.AprEndpoint$Poller.run()" thread.
And this exception meaning is: somewhere native code tried to write on a memory and it failed.
These are my temporary solution suggestions for now:
- Upgrade tomcat to 8.0.47. Looks like some bug-fixes talk about APR issues.
- Upgrade APR to latest available.
- Disable APR by removing the .dll file.
Since I don't have the root cause m not confident on any of above solutions.
Please do correct me if I am wrong in my analysis up till now.
We are trying to find root cause of this issue. Can anyone help us with it?
Let me know if it needs full crash log or memory dump to analyze further.
