-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, Philip,
> I tried to reproduce your problem without using OpenVZ. thanks for trying! (Though I don't think you have succeeded.) To follow your request, while the stuck download was running and getting nowhere, I did two "ls -laR" on the client's working directory. The crucial big-stupid-binary-file.bin.svn-base was at a bit of 3 MB before the 20 seconds and at the same bit over 3 MB afterwards, with not a byte of progress having been made in 20 seconds. Find the precise information at the end of this message. The entire single 10 MB file checkout normally happens in about 7 seconds. I'm not complaining about "slow". I'm complaining about "no progress at all" and "endless loop". Also, I tend to see no openvpn activity, so apparently no serious amount of network traffic. Just to rule out openvpn as a source of trouble, this time, I have used an ssh tunnel. I set it up via ssh -L 7777:vzclientip:7777 r...@vzhost and used it via cd /tmp; svn co localhost:7777 bug resulting in the buggy behavior. This was actually the setup I used for those two ls -laR . For the record: The SVN server is back to version 1.5.1 from Debian Lenny. With the server still spinning, I can kill the svn client. Mild "kill"s don't lead to any results. But, of course, "kill -9" does the trick. After that, I wait for another 20 seconds. Even now, 20 seconds after the death of the partner (that is, almost three times longer then the entire check out normally takes), the svnserve is still at 99.something % CPU load. It continues to be there until I kill the server. So, imho, that's your "holy grail" to seek ;-) . That is, I speculate if you can reproduce "99+% CPU load without client", you have indeed reproduced my problem. For the record: In a different experiment leading nowhere, I have tried a few-line Perl script as a server, generating junk data. The client, also a Perl script, actually double-checked it got the precise junk the server had sent (as, of course, should be the case with TCP/IP). Both were derived from what's in "man perlipc" under the heading "Internet TCP Clients and Servers". Between those two, there was no problem transferring 50 MB of data, even with ridiculously low tcpsendbuf. I think 50k:350k is what I used at that time. So, as I said, this line of investigation lead nowhere.
