similar to: MySQL On ZFS Performance(fsync) Problem?

Hi there, I know this is off-topic or semi off-topic but I really need some help since I am stucked. I'm trying to redirect MariaDB logs to `/var/log/mysql/*.log` files as shown below on the `/etc/my.cnf.d/server.cnf` file: # # These groups are read by MariaDB server. # Use it for options that only the server (but not clients) should see # # See the examples of server

When using the host personality, VMCI will grab a mutex for any queue pair access. In the detach callback for the vmci vsock transport, we call vsock_stream_has_data while holding a spinlock, and vsock_stream_has_data will access a queue pair. To avoid this, we can simply omit calling vsock_stream_has_data for host side queue pairs, since the QPs are empty per default when the guest has detached.

Hi, Please advise how to use Response Rate Limiting on a server which has multiple NSD server processes (nsd.conf server section has server-count > 1). We have a problem with NSD v3.2.16 repeatedly unblocking and blocking again a single source which is flooding positive queries at a ~steady 700 qps rate. rrl-ratelimit setting is the default 200 qps. The unblock-block happens multiple times

In the past week, working with Samba 3.0.23d and the Linux 2.6.20 kernel, I have observed something interesting about Samba and the utilization of multiple CPU cores. On a single Dual Core 3 Ghz Xeon machine, when I am hammering the Samba server with requests from many client machines, a variety of CPU utilization tools like Gkrellm and Qps show that CPU utilization is around 30+ percent on

I have two HP dc7800 convertible minitowers that are exhibiting the following issue: every 5-10 minutes, they will "freeze" for about 30 seconds, and then pick right back up again. During the freeze, it seems that nothing at all happens on the system; the clock doesn't even advance (it just picks up again with the next second, and that 30-or-so seconds are lost). I've tried both
