Hi list,

I've got the "Mesg read: Connection reset by peer" problem

I see in the dumper.debug file on the server this line

dumper: time 27813.730: (sockaddr_in6 *)0x904c30 = { 10, 10080, ::ffff:145.238.170.197 } dumper: time 27873.720: security_seterror(handle=0x8c66c18, driver=0x8e2be0 (BSD) error=timeout waiting for REP) dumper: time 27873.720: security_close(handle=0x8c66c18, driver=0x8e2be0 (BSD))



and in the sendbackup.debug client
1223337320.985634: sendbackup: gnutar: /usr/libexec/amanda/runtar: pid 320
1223337320.985688: sendbackup: Started backup
1223339253.419941: sendbackup: critical (fatal): index tee cannot write [Broken pipe]


In the wiki we can use "/proc/sys/net/ipv4/tcp_keepalive_time" parameter but I don't find it for ipv6.

What i've unsterstood is that my tar of the dle on the client make the computer too busy and he is loosing the connection. ( but the two another dle entry on the same client works great /home and /etc )


What can i do ? the DLE is 700 G used for 1 T ( many files ). the computer seems to be busy ( some physics computing ) when the backup start

this DLE is nfs exported. I read before that's important to said.
Should i stay on ipv6 but change the dump style ( tar -> dump)
try connect with ipv4 and change the keepalive or change the security method ( auth=bsd -> auth=tcpbsd )

thanks for helping me


julien
