similar to: pop3-login process leakage

Running dovecot-0.99.13 on Solaris9/Sparc with ~25k users, we are having regularly recurring problems with large numbers imap-login/pop3-login drones, cycling on poll(). Over the course of 1-2 days, the number of such processes slowly rises to >1000, exhausts resources, and necessitates that dovecot be restarted (having killed all current active and zombie child processes). Nothing of

Are you still facing the problem ? If so, Can you please provide the workload , cmd_log_history file, log files , etc ?

Hi All, We are using GlusterFS 3.10.2 (upgraded from 3.7.0 last week) on CentOS 7.x . We continue to see memory utilization going up once every 3 days. The memory utilization of the server demon(glusterd) in ?server is keep on increasing. In about 30+ hours the Memory utilization of glusterd service alone will reach 70% of memory available. Since we have alarms for this threshold, we get notified

Hi, Thought I'd just forward this here, because I don't have time to look into it right now, and am off skiing next week. I'd guess that we should be checking for username = ``root'' before going off to do password checks, and rejecting it on that basis first. Cheers, Phil. -- Mind-numbingly stupid UK law alert!

When I repeated restarting VM or define and undefined VM during my recently test, memory leakage of xend is detected. Our elementary conclusion is that the python memory management mechanism causes this problem, but I do not know how to further locate the exact lines. Can anybody here give me any suggestions? Thx.

Hi, all: I'm using R 1.7.0 on WinXP under SDI mode. However, very often after I closed all R windows, my CPU usage was still 100%. By checking the task manager, I found there are one or several "Rgui.exe" still running and took all the CPU. I had to close them one by one manually. This happened to me with R 1.6.1, R 1.6.2 also and also on Win2K. Rememeber there was a

So one of my coworkers is doing a little research on SSH usage in the wild using netflow data. One of the things he's trying to do is determine a way to differentiate between data transfers and interactive sessions. We thought of a couple of ways but we wanted to float them here and see if there are methods incorporated to defeat thi sort of traffic analysis. The first idea is to look at

editors note: just now found something about IdentitiesOnly that might do the trick. there's some other stuff in here too. about preventing info leakage [keys for other sites] from appearing in the client<-->server key negotiation with ssh-agent and IdentityFile. ssh/config:IdentityFile - seems to indicate that only the specified key will be tried, and if that key fails, no other keys

Hi, Was this ever resolved? I'm curious, I'm also in a situation where there may be many (very many) JITted functions over the history of an application (which may be running for many days) Thanks On Mar 20, 2009, at 7:34 AM, George Giorgidze wrote: > Hi, > > In my application I am JITing thousands of functions, though I am > doing it sequantially and running only

Dear All, <<OS and software>> R-1.81 j2sdk1.4.0_03 SJava_0.66-1 Windows NT4.01 I try to run R from Java with SJava and I seem to have the same problem as discussed before in this mail list a few month ago: https://www.stat.math.ethz.ch/pipermail/r-help/2003-May/031960.html https://www.stat.math.ethz.ch/pipermail/r-help/2003-May/031962.html

Hi guys, and here's a security related bug report. I think it's has been fixed in the 2.2.x-release of openssh, but I'm not sure. I tried to reproduce the problem with my 2.2.0p1 and could find any difference in the behaviour of ssh depending on wether PermitRootLogin was set to no. Could someone please confirm that this problem is not existing anymore? > When PermitRootLogin is

Hi, In my application I am JITing thousands of functions, though I am doing it sequantially and running only one at a time. So it is crucial to be able to properly clean up the memory from an old JITed function when JITing and running the new one. I am using Haskell binding of LLVM and my application works OK. However, memory usage increases and never decreases during the run time of my

Pinned pages are not properly accounted particularly when mapping error occurs on IOTLB update. Clean up dangling pinned pages for the error path. As the inflight pinned pages, specifically for memory region that strides across multiple chunks, would need more than one free page for book keeping and accounting. For simplicity, pin pages for all memory in the IOVA range in one go rather than have

Hi, I've spotted a possible memory leakage/violation in the latest R v2.1.1 patched and R v2.2.0dev on Windows XP Pro SP2 Eng. I first caught it deep down in a nested svd algorithm when subtracting a double 'c' from a integer vector 'a' where both had finite values but when assigning 'a <- a - c' would report NaNs whereas (a-c) alone would not. Different runs

Hello, I am experiencing a very noticeable memory leak when using large lists of large data. The code below creates a list of matrices, yet the memory does not free up after removing that item and performing a garbage collection. Is there a something I can do to prevent this memory leak? Any help would be greatly appreciated. By the way, if you execute the code, please run it in a new R session.
