Hi, I have a eaton 1500 that connects to an Ubuntu Xenial box via USB. The UPS works, however exactly *ever 5 minutes* it disconnects and reconnects and I see this in syslog: Mar 10 19:50:32 spike kernel: usb 4-5: USB disconnect, device number 103 Mar 10 19:50:33 spike kernel: usb 4-5: new low-speed USB device number 104 using ohci-pci Mar 10 19:50:34 spike kernel: usb 4-5: New USB device found,

Hi, I've been getting regular CPU usage spikes(50%-80%), due to asterisk (according to top). I never noticed this on 1.4, and I have top running in the background pretty much all the time. In between those spikes Asterisk stays under 10% CPU usage (I have a transcoder card, which helps). It's very regular, never any missed spike, or an...

Arno, thanks for taking the time to write back and no worries about lag, we're all busy and I'm grateful there is a community to interact with to begin with. You're right - the problem went away once I actually configured nut. I guess I was too "cautious" and when I saw the errors I thought something was wrong with the usb connection and didn't try to get nut going

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, -- Robert Merithew

...lls without an issue. Can it possibly be a bug? if not how do I profile which call(s) can be causing the spike?

...th what I assume is looping packets. 200-300MB of bandwidth per node over 10-45 minutes (normally < 20 KB/s, idle). Most if not all nodes participate in the spike. Some nodes just have a spike on output, some only on input. ? I see a bunch of these lines in the logs on all the servers with the spikes, each about one or two other nodes: ``` Got late or replayed packet from <NODE_NAME> (<INTERNAL_IPv6_ADDRESS>%<NETWORK_NAME> port 655), seqno 235266, last received 235410 ``` ? What causes this and is there a way to prevent these spikes? I estimate an extra 4-5GB of extra band...

...has an IVR that plays random gsm files. The box has SSD's and two CPU E5-2695 v2 cpus with 64GB ram. The Asterisk CPU usage along with the load seems to jump around. With about 500 callers it hovers between 250-400% CPU (so 2.5 to 4 cores) which seems reasonable. Every so often the load average spikes. The idle never drops below 85%. When the load average spikes I see a lot of kworker threads and the CPU usage tends to (not not always) go up as well. How would I go about seeing what in Asterisk is causing the spike? The box is locked down and only takes calls from an OpenSiPS box. There is nothi...

..., +/- 1003 interrupts/sec., less than 10 context switches/sec., CPU idle 100%. A very quiet system. I load modules zaptel and wcfxo, and the system utilization stays the same. When I load wcfxs, the number of interrupts goes up to +-2004, which is normal. However, every three seconds the CPU spikes to 50%. This is "system" utilization, not userland. I assume it's in a wcfxs interrupt. The number of interrupts stays constant at about 2004 during each spike, leading me to the conclusion that the TDM card is holding an interrupt for 500ms every three seconds (50% of 1000ms is...

Right. I had thought so too (and forgot to mention

I'm setting up a dovecot server with private and shared namespaces. My test setup has these mailboxes: # /bin/doveadm mailbox list -u fdl01 at spike.test INBOX/sub01 shared shared/sammel01 at spike.test shared/sammel02 at spike.test INBOX In order to do some post-login scripting foo I'd like to get a list of shared mailboxes the user is currently subscribed to.

...on a completely idle system with only the zaptel drivers loaded. I used 'vmstat 1' to monitor this. I was using the wcfxo driver (wildcard fxo) as a timing source. After switching to the ztdummy driver and using the usb controller as a clock source, I observed that the frequency of the CPU spikes changed to approximately every 5.5 seconds. Hmm... Also, as additional channels were added to the system, the CPU spikes increased in intensity (ie: from 15% utilization to 50% each spike). Further research indicated that many folks using various flavors of FXO cards were experiencing similar obs...

...words the CONDITIONAL CORRELATION of lag 2 given lag1 PACF(k) estimates the correlation between y(t) and y(t-k) adjusted for the effects of y(t-1), ..., y(t-k+1). Model identification is achieved by looking at the pattern of the ACF and PACF. - If the ACF dies off exponentially, but the PACF has p spikes, AR(p) is indicated. - If the ACF has q spikes and the PACF dies off exponentially, MA(q) is indicated. The ACF and the PACF for the resulting stationary series is used to determine the best B/J model for the series according to the following rules: a. If the ACF trails off and the PACF shows...

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

Hi all, My server is connected to a UPS but whenever there is a power failure or spike it seems that once all the clients come back up they cannot connect. I have to restart the server each time. This is no hardship but I was just wondering if anybody had the same problem and if so and they fixed it, how? Thanks Tom Ansley

...oo long. I have all unnecessary services switched off and X is not running when I perform these tests. Some transmission are successful while others fail at random points. I've noticed that after I boot Linux, load zaptel, wcfxo, and wcfxs, and then run System Monitor, the CPU utilization spikes to 60% every 10 seconds. After I remove wcfxs the spikes stop, and system utilization stays at 0%. I have two TDM22B cards and get these spikes with either card in the system. This is an Athlon-64 3000+ CPU and Fedora Core 2. zaptel-1.0.2. Is there anyone who has a TDM card on a "quiet&...

Hi All, I have a problem (at least I think it's a problem) where the wcfxs module causes constant CPU usage spikes. The card being used is a Digium Wildcard TDM400P with 3 FXO modules and 1 FXS (TDM31B). Monitoring my otherwise idle asterisk box (with top) I see once every 3-5 seconds hi (hardware interrupt) spike to 30%-40% and then drop back to 0 again. This is the case wtih both asterisk stable and CVS HEAD...
