Ticket #5107 (closed defect: duplicate)
Downloading via NAT connection hogs 100% CPU and never finishes
|Reported by:||spectre||Owned by:|
Sometimes when I try to download a bunch of files that amount to at least a dozen megabytes, the guest system begins using almost 100% CPU and becomes nearly unresponsive, the download almost freezes (perhaps it runs but extremely slowly).
The problem appeared, for example, when I was trying to perform an online update of Ubuntu 8.10 guest (25-290 Mb of packages were to be downloaded) or was doing something like
svn co svn://svn.valgrind.org/valgrind/trunk valgrind
(about 85Mb or more to be downloaded).
If I was downloading something not very big (a couple megabytes or less), no problem occured.
I tried VBox 2.2.4 - the problem did not show up there.
I have attached the log from VBox 3.0.6 running online update of Ubuntu 8.10 (eventually I had to kill VBox this time) and from VBox 2.2.4 where the same operation completed successfully.
Host: Windows XP SP3 Pro x86 The problem has showed up on the following guests: OpenSuSE Linux 11.1, Ubuntu Linux 8.10. I have not tried to reproduce it on other guests yet. Network: NAT with PCNet Fast III adapter. I tried also Intel PRO/1000 MT Desktop - the same problem there.
