dovecot/auth CPU spikes
Hi All,
I have recently moved by webmail server from a VPS to a hosted dedicated server running Ubuntu 16.04.
Everything is fine except that login is particularly and consistently long (around 4-5 seconds).
I have noticed that the process dovecot/auth seems to eat all of the resources of one of the cores available on the host during login. The authentication backend is a postgres database which

dovecot-imapd eating 100% cpu every once in a while
Hello,
About once or twice a week, dovecot's imap-login process on my system
seems gets out of control, eating 100% CPU for about 2 hours. Afterwards
everything seems to go back to normal.
I am using Dovecot 2.1.7 on a 64 bit Debian wheezy system.
When running gdb on the process in this stage, I get the following
traceback:

smbd's using up 100% of all cpu's and load avg slowly going up
Hi,
Yes, I already thought about it.
I have the sernet repo installed.. Is possible to yum update and jump
from 4.1.6 to 4.1.14 directly, without problems or should I follow some
kind of procedure to avoid future problems?
Regards,
Bruno Andrade.

STAR (Spike Train Analysis with R) uploaded on CRAN
Hi all,
I've uploaded STAR (Spike Train Analysis with R) on CRAN two days ago.
The package is designed to analyze neuronal spike (action potential)
trains. It uses S3 classes and methods and makes heavy use of other
CRAN packages like gss, R2HTML, mgcv, survival.
* Analysis of both spontaneous and stimulus evoked activity is
implemented for single neuron spike trains as well as for many

fit to spike with exponential decay : optim() question
I finally got (mostly) what I wanted. In an attempt to figure out how to
get nls to deal with a non-differentiable function, I had (stupidly)
'simplified' the problem until it became singular.
Can I do something to make optim() less sensitive to my initial guess? For
this example, I get a lousy solution if I make the initial guess for t0 =
min(t) = 0.05.
Thanks again,

Context Switches and Load Average spike - Asterisk Version 1.4.22
I am running Asterisk V 1.4.22
Twice during the last two days the Context Switches on our box has gone from

When connecting to the console 'core show channels' will list the channels

Outbound traffic spike every 30 minutes
Since Sunday morning, one of my CentOS servers has been generating a
small spike of outbound traffic every 30 minutes (X:00 and X:30). It's
not enough traffic to really cause any notice except for the fact that
it is a very regular pattern and it started abruptly at midnight Sunday.
This server is used for mail (Courier-MTA), and DNS (Bind). I cannot
find anything unusual in either of
