FrostWire crashes at random when left unattended


We've seen this issue happen on Windows XP, but it could be relevant for other versions as well.

The issue seems to be caused by NVIDIA ForceWare Network Access Manager. It's known to increase CPU consumption and software crashes.

Nvappfilter.dll has also shown certain incompatibilities with uTorrent and Azureus. uTorrent has warned that nvappfilter.dll may even cause the program to crash, use up all of your RAM and freeze your system.

There have also been complaints from users that downloaded files are often corrupted. Some users have also complained that the machines with the nvappfilter.dll file had problems discerning the LAN speed of the network the machine was connected to.

How to diagnose that is indeed the issue?

Run FrostWire in the safe mode and read the output on the console window behind it. If you see a file named Nvappfilter.dll mentioned somewhere with the words error, you are on the right track.

It could say something like:


A fatal error has been detected by the Java Runtime
EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x24325387, pid=2672,

JRE version: Java(TM) SE Runtime Environment (8.0_11-b12)

Java VM: Java HotSpot(TM) Client VM (25.11-b03 mixed mode
windows-x86 )

Problematic frame:
