I'm facing a problem with dovecot 1.0 test-59; ever since I installed it and use it my random pool is always depleted whenever someone opens an imap connection. This wouldn't be too bad if the machine was used interactively, but since it is not and other services read directly from /dev/random those are sometimes blocked due to dovecot depleting the pool by reading /dev/urandom. Thus my question: is it re...

Dear all, I'm performing a t-test on two normal distributions with identical mean & standard deviation, and repeating this tests a very large number of times to describe an representative p value distribution in a null case. As a part of this, the program bins these values in 10 evenly distributed bins between 0 and 1 and reports the number of observations in each bin. What I have noticed

There are cases that users want to shrink balloon pages after the pagecache depleted. The conservative_shrinker lets the shrinker shrink balloon pages when all the pagecache has been reclaimed.

...s between each user-add As you can see, in "CN=RID Set,CN=DC1,OU=Domain Controllers" rIDNextRID increments by one between each user, but there is a new rIDAllocationPool each time. And to match that, inside of the "CN=RID Manager$,CN=System" container the rIDAvailablePool gets depleted by 500 between each new user. Is this normal behavior, or a bug? I thought the DC only requests 500 additional RID's when it was close to being depleted - not on each object addition. == Thu Jul 11 20:45:59 EDT 2013 ===================== dn: CN=RID Manager$,CN=System,DC=ad,DC=domain,DC=com...

From: Willem de Bruijn <willemb at google.com> Vhost-net has a hard limit on the number of zerocopy skbs in flight. When reached, transmission stalls. Stalls cause latency, as well as head-of-line blocking of other flows that do not use zerocopy. Instead of stalling, revert to copy-based transmission. Tested by sending two udp flows from guest to host, one with payload of

I am curious about why the Interrupt Out packet is sent by the Windows software if it isn't to turn off the UPS. Is it possible to do some more testing with shorter timeouts so that the battery doesn't get depleted? You would need to r...

We should probably log the status changes at level 2 or less, since the hex dump is only useful for those who know the protocol.
