Description
Hello,
On a router with the following details I am seeing a memory usage pattern that looks to be out of the ordinary to me:
I2P version: 0.9.19-0 Java version: Oracle Corporation 1.7.0_76 (OpenJDK Runtime Environment 1.7.0_76-b13) Wrapper version: 3.5.20 Server version: 8.1.16.v20140903 Servlet version: Jasper JSP 2.1 Engine Platform: FreeBSD amd64 10.1-RELEASE-p6 Processor: Sandy Bridge H/M (corei) Jbigi: Locally optimized native BigInteger library loaded from file Encoding: UTF-8 Charset: UTF-8
I have attached two graphs plotting average memory used, one for a short time interval and the other for a longer time interval.
Please take a look.
Thanks,
xmz

So ordinary to me, is stable memory usage. Out of the ordinary are the spikes which nearly use up all available memory.
This may help track down the cause of this memory usage pattern:

Patterns like that are generally caused by client activity, e.g. running some i2psnark torrents for a while, then turning them off (or having them complete). Going floodfill and then non-floodfill is also a possibility.
If the memory usage kept going up, we'd call it a memory leak somewhere, but if not, it looks normal to me.
In any case, there's not enough information here to be able to investigate. If you have any other info, please provide it.

Closing. Nothing unusual.
