https://bugzilla.novell.com/show_bug.cgi?id=231234 Summary: Sometimes desktop hangs for some time, with an nfs mounted home Product: openSUSE 10.2 Version: Final Platform: 32bit OS/Version: Linux Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: richard.bos@xs4all.nl QAContact: qa@suse.de Sometimes desktop hangs for some time, with an nfs mounted home this happens after a upgrade to opensuse-10.2. Before 10.2 this behaviour was not present, neither on 10.0 nor 10.1. Perhaps the problem has to do with those bugs to: Bug 227645 - NFS has upload limt of 50 KB/s https://bugzilla.novell.com/show_bug.cgi?id=227 Bug 229848 - unable to access certain web sites https://bugzilla.novell.com/show_bug.cgi?id=229848 I have not been able to debug/benchmark my nfs setup as described in bug report 227645: *Tested diffrent blocksizes (1024, 2048, 4096, 8192, 16384 and 32768) and benchnmarked them with: # mount files.first.com:/home /mnt -o rw,wsize=1024 # time dd if=/dev/zero of=/mnt/test bs=16k count=16k Every benchmark had around the 25 MB/s If I do that I get: # time dd if=/dev/zero of=/mnt/test bs=16k count=16k dd: opening `/mnt/test': Permission denied real 0m0.003s user 0m0.000s sys 0m0.004s I don't know what is the reason for that. I have a wireshark dump of 55MB, that shows some interesting output, perhaps you want to receive this? Before I attach it to the bugreport, I'll provide an ascii dump of the headers. A short dump of output follows below:
grep " 430[89]." wireshark.out | cut -c65- RPC Continuation RPC Continuation RPC Continuation TCP [TCP Window Update] nfs > 972 [ACK] Seq=2447796 Ack=87180476 Win=8500 Len=0 TSV=43593242 TSER=10607958 RPC Continuation RPC Continuation RPC Continuation RPC Continuation RPC Continuation RPC Continuation RPC Continuation TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU] TCP [TCP segment of a reassembled PDU]
On a correct working system, I think that the "RPC Continuation" and "reassembled PDU" shouldn't be there. I can't remember I saw those on systems prior to 10.2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
