Author: Volker Lendecke <vl at samba.org>
Date: Fri Mar 26 13:18:52 2010 +0100
s3: Use tdb_transaction_start_nonblock in gencache_stabilize
This avoids the thundering herd problem when 5000 smbds exit simultaneously
because the network went down.
commit d5fd1f207757b4f15d15b8744db0c9380fe63cab
Author: Volker Lendecke <vl at samba.org>
Date: Fri Mar 26 13:15:53 2010 +0100
Revert "s3: Optimize gencache for smbd exit"
This reverts commit 5ca63676dc59e83ffd9560fdcfa26063f267f283.
That does not fully fix the problem, adding a tdb_transaction_start_nonblock to fix it.
