Hi list!
We have a problem with our samba server (version
3.0.14a-1 running on SuSE Enterprise OS). After some
time of inactivity (about 15 min) the clients get some
delay when they reconnect to a share. When the want to
open a document it takes about 5-10 secs until it
opens. After first reconnect everything work fine.
Which parameter could i change to fix this problem?
I already tried deadtime, keepalive, SO_KEEPALIVE and
serval other.
Server hardware: Intel Xeon 2,8 GHz, 2,5 GB RAM, 2
giga nics and SAN hdd.
server:~ # hdparm -Tt /dev/sdb
/dev/sdb:
Timing buffer-cache reads: 128 MB in 0.20 seconds
=640.00 MB/sec

Here is my config.
