Timo / Others, I have been working on a new installation for a fairly busy site, and after many weeks of tribulation have come to an architecture Im happy with: 2x Debian (2.6.18) - MXing machines running Postfix / MailScanner / Dovecot-LDA (A slightly patched RC17 for prettier Quota bounces) 2x Debian (2.6.18) - Mail retrieval machines running Dovecot IMAP/POP3 (Currently RC17) 3x Node Isilon

https://bugzilla.netfilter.org/bugzilla/show_bug.cgi?id=485 ------- Additional Comments From bugzilla.netfilter@neufeind.net 2006-06-06 02:00 MET ------- I tried to track down the problem meanwhile. It turns out that e.g. in a row of roughly 480 "ipset -A" (nethash) in a row the system once hangs at around 300 executed statements while it hangs around 370 the next time. So this

Hi all. I currently have a CentOS 5.8 x64 host. I have some info that it is "slow" for end users. I would like to use some tools to make tests of proc/memory/disks. Is there a program suite which you could recommend? Best regards, Rafal.

Hi all, I am trying to write a program that sends SIP requests to asterisk. My aim is to make asterisk record as many voicemails it can at a time. The design of the program is like this: There are two processes: One main process and a child process (No flames pls. I have very little idea about pthreads and dl modules) The main program asks the user to input the number of test instances. When

I encountered while stresstesting the reclocking code, that rarely (1 out of 20.000+ requests) we don't get any IRQ in nvkm_pmu_intr. This means we have a queued message on the pmu, but nouveau doesn't read it and waits infinitely in nvkm_pmu_send: if (reply) { wait_event(pmu->recv.wait, (pmu->recv.process == 0)); therefore let us use wait_event_timeout with a 1s timeout frame

Fixes runpm breakage mainly on Nvidia GPUs as they are not able to resume. Works perfectly with this workaround applied. RFC comment: We are quite sure that there is a higher amount of bridges affected by this, but I was only testing it on my own machine for now. I've stresstested runpm by doing 5000 runpm cycles with that patch applied and never saw it fail. I mainly wanted to get a discussion going on if that's a feasable workaround indeed or if we need something better. I am also sure, that the nouveau driver itself isn't at fault as I am able to reproduce the s...

We're talking about a bunch of different stuff which is all being conflated. There are 3 issues here that I can see. I'll attempt to summarize what I think is going on: 1. Current patches do a hypercall for each order in the allocator. This is inefficient, but independent from the underlying data structure in the ABI, unless bitmaps are in play, which they aren't. 2. Should we

Both patches should make the communicating with the PMU more stable.

...Ponly and IndirectData are back (but not fully tested). - Documentation revised, it's really up to date with the released package now. - tincd -K now stores public/private keys in PEM format, but keys of 1.0pre3 can still be used. - Faster and more secure encryption of tunneled packets. - Stresstested to see if it handles large VPNs with more than 100 sites (it does). Again, due to the large changes in the protocols this version does not work together with older versions. However, you don't have to change the configuration files this time. Most of the things we wanted to include in 1.0...

Hi, I just finished setting up a functional design with Dovecot+Sieve and it works like a charm. However I'm having serious doubts about the scalability of this. Here is part of a discussion we're having here: About Dovecot+Sieve. What happens here is that your MTA is configured to pass _all_ email to Dovecot which is configured as a LDA. In practice this means this in the Exim
