I doubt that this patch would affect my dbench runs because I wasn't getting any network reconnections (they would have logged a warning to dmesg) and the fix is in reopen_file (which is invoked on reconnections).
I am updating and building current samba3 on a different machine (the one I more frequently run dbench test runs on) to check on whether this is an Ubuntu specific limit which I had not seen before (I usually run dbench with 50 rather than 60 processes). The Samba handle limit should (and was) be quite large.
In any case, as long as we are sure we are hitting a Samba server limit (or server side per-process limit), we are ok and can continue to review/merge the very large inode patches. I am verifying with one additional pair of temporary stats (counters of successful opens) in the exit path of cifs_open and cifs_close) to make sure that those match what I have already verified that we are seeing with smbstatus and the client side counters on number of successful posix_opens.
-- Thanks,
Steve
