similar to: Tinc Network Spikes

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 any spike in between the regular spikes. I

I need to reopen this discussion because it's impossible to run spandsp (and VoIP) under these circumstances. With zaptel unloaded, I see the following "vmstat 1" output: no swapping, an occasional disk output, +/- 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

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

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

Digging further into the FXO cpu spike vs clock issue, I removed the 18.432 MHZ crystal from an FXO card and replaced it with a 20.000 MHZ crystal. This of course forced the zaptel timing way off ~ 93% accurate using ztclock. I then proceeded to modify the wcfxo.c driver source code to set the proper PLL divider values to return the DAA clock back to 8 Khz. I came up with the values of N1=25,

R Friends, I have data from which I would like to learn a more general (smoothened) trend by applying data smoothing methods. Data points follow a positive stepwise function. | x x | xxxxxxxx xxxxxxxx | x x |xxxx xxx xxxx | xxxxxxxxxxxxxxxxx | |

Hi, very periodically, we see I/O hangs for about 10 seconds, roughly once per minute. Each time this happens, the I/O rate simply drops to zero, and all disk access hangs; this is also very noticeable on the shell, for NFS clients etc. Everything else (networking, kernel, ?) seems to continue normally. Environment: FreeBSD 9.1R GENERIC on amd64, using ZFS, on a ARC1320 PCIe with 24x Seagate

Hello, I think routing could be improved in several ways, at least, there lacks some documentation describing how Tinc routes packets. In order to test Tinc, I setup the following virtual network: - tinc 1.1pre9 with ExperimentalProtocol=yes - use of network namespaces (actually python-nemu[1]) - star topology, where all nodes runs tinc except the center, which I use to filter communications,

I've made some modifications to zttest in order to use it as a frame clock accuracy tester / slip detector. I'm not certain if that was it's original purpose, but it seems that a lot of folks try to use it that way. The result is something that I'm calling ztclock for now to help avoid confusion. I'm including the source at the end of this post. You can compile it by placing

Hi all, I tried Tinc 1.1 from git on 4 nodes, each one in a datacenter. They were able to ping each other, etc... but I had problem with multicast, nothing seemed to pass (all is OK with Tinc 1.0.23). I checked logs and on every nodes I have a lot of: Failed to decrypt and verify packet And Error while decrypting: error:00000000:lib(0):func(0):reason(0) So I get back to 1.0.23 which works

Is SPTPS protocol enabled in 1.1 by default? Or we need to manually enable it. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://www.tinc-vpn.org/pipermail/tinc/attachments/20180316/2360e357/attachment.html>

Is it just me, or does anyone else experience their CPU utilization spiking to 100% for about 5 to 10 seconds when Firefox is about to download a file, via http or ftp? Then, after the file starts to download, the CPU usage drops back down to normal. I've got Firefox 2.0.0.4 running on CentOS 4.4 32-bit. Thanks. Scott

With pleasure we announce the release of tinc version 1.1pre10. Here is a summary of the changes: * Added a benchmark tool (sptps_speed) for the new protocol. * Fixed a crash when using Name = $HOST while $HOST is not set. * Use AES-256-GCM for the new protocol. * Updated support for Solaris. * Allow running tincd without a private ECDSA key present when ExperimentalProtocol is not

The following matrix of normed likelihoods should give a smooth surface but instead gives a series of spikes in both persp and contour (the dim labels are the axes values). I know an algorithm cannot be infallible but it would be nice to have some parameters to control the smoothing. (It takes close to an hour to produce this matrix on a Pentium II 300mh. It was after that that it crashed with the

Because of a security vulnerability in tinc that was recently discovered, we hereby release tinc versions 1.0.21 and 1.1pre7. Here is a summary of the changes in tinc 1.0.21: * Drop packets forwarded via TCP if they are too big (CVE-2013-1428). Here is a summary of the changes in tinc 1.1pre7: * Fixed large latencies on Windows. * Renamed the tincctl tool to tinc. * Simplified changing the

Hi. I'm in desperate need of some good advice. I have a tinc network with 16 nodes. It's a star topology where all nodes are connecting to the one node (Node1) that have a static IP. Node 1 accepts incomming connections Node 2 through 16 connects to Node1 One of the nodes (Node5) stopped working a while ago (2 - 3 weeks or so), other than that everything was working fine. Today I

Hello, I'm trying to investigate and solve some postgres latency spikes that I'm seeing as a result of some behaviour in the syncer. This is with FreeBSD 8.2 (with some local modifications and backports, r231160 in particular). The system has an LSI 9261-8i RAID controller (backed by mfi(4)) and the database and WALs are on separate volumes, a RAID 6 and a RAID 1 respectively. It has
