Can you add PrintReferenceGC to print out number of references for each gc?
Thanks

I didn't have verbose gc enabled but I did enable it, and here is the

The "Full GC" is related to a jmap -histo:live I was running.

Can you upload the verbose GC log somewhere? I suspect you don't
see old/mixed GCs since 30h.

*Subject:* SoftReferences not cleaned up
Hello,
I have problems understanding why the SoftReferences are not
cleaned up. This is my version of java:
java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)
and I run it with the options -Xmx512m -XX:SoftRefLRUPolicyMSPerMB=1
Still the number of SoftReferences keep increasing and I see that
some of them are 30+ hours old. I have a heap dump:

<https://drive.google.com/open?id=0B8_hkIRtZSShNUtTZUx3UTFuMEk>
I don't know how to debug further, any hint would be appreciated.
thanks,
nicolae
