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

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
