comment Postfix mailqueue “Mailbox Full”
Sounds like the alarm is not tuned correctly, but it is hard to tell without knowing the use case. I would not worry so much about the length bounce queue. We do have a similar alarm, but it is configured to go off on sudden changes in the number of messages successfully delivered.

comment Postfix mailqueue “Mailbox Full”
@Ricardo: Is it an actual, measurable, performance problem? My experience is that there are many other things with a larger impact on the performance of the mail server than the length of the bounce queue...

comment Apache version 2+ doubles the TimeOut directive on requests
TimeOut is part of the low level I/O configuration in the Apache core. It's a kind of safety to prevent I/O operations that have blocked from locking the webserver. While I can't really explain the behavior it is not the normal way to control the execution time of PHP scripts. That you usually do with max_execution_time in the php.ini file.

comment Scheduler spikes single core on SMP Ubuntu vm under ESXi
Seems to have the same behavior with compression turned off, but it is not as noticeable as the dump becomes network-bandwidth bound.

comment Scheduler spikes single core on SMP Ubuntu vm under ESXi
Can't reboot the server, so changing the number of vCPU isn't really an option at the moment. The hardware has an Intel E5540 CPU and about 16 GB of RAM. And it is indeed just the dump command piped over SSH to move the data to a backup server. I run it in parallel for all partitions in the system.

4 core hardware, configured with 3 vCPU for this VM. It's an old configuration, I don't know the details of why it was setup like this.
