OutOfMemoryError, NullPointerException for normal install

[anonymous]

I found a java.lang.OutOfMemoryError? and more following that one in the logfile of my router version 0.7.11-0.

The JVM was started using the default commandline:

The logfile shows a couple of OutOfMemoryError? s and NullPointerException? s leading to an unexpected shutdown:

I should add JVM info:

SAM and BOB plugins were both running i think, and no other plugin

and the other info from ​http://127.0.0.1:7657/logs.jsp

I'll fix the NPE, but there's nothing to do for the OOM except increase the memory limit in wrapper.config.

net.i2p.router.Router : free mem: 16112 total mem: 133234688

One cause of high memory usage is running a lot of torrents in i2psnark, or running SAM - SAM uses a lot of memory and may have some memory leaks too.

[zzz]

NPE was fixed in 0.7.12.
