* cross posted to the mongrel mailing list* Hi, I''m running into a strange issue where one mongrel will sometimes develop hundreds of CLOSE_WAIT TCP connections, mostly to apache (I think -- see sample lsof output below). I haven''t had a chance to get the mongrel with this behavior into USR1 debug mode yet. I wrote a little loop below that will catch it next time. This issue occurs a couple times a day on average at seemingly...

Hi, I''m running into a strange issue where one mongrel will sometimes develop hundreds of CLOSE_WAIT TCP connections, mostly to apache (I think -- see sample lsof output below). I haven''t had a chance to get the mongrel with this behavior into USR1 debug mode yet. I didn''t catch it in time. This happens a couple times a day on average at seemingly random times.

Hello samba people. I am having a odd problem related to winbindd. When I leave it running overnight on a quiet (not silent however) server I find that it generates a large number of CLOSE_WAIT state connections. 84 on a fairly quiet system in the last 18 hours. I can't seem to find any command that directly affects the number of CLOSE_WAITS. Below is my netstat listing. Any ideas would be helpful. I looked around but could find no reference to this problem. I am running in SECUR...

...an keeping lots of open connections to the MySQL server (as far as I understand it opened one connection for each client run and never closed them). I set up the server to close idle connections after 5 minutes. Now the database server does close the connections but the puppet master keeps them in CLOSE_WAIT state and eventually runs out of file descriptors. Here is a sample of the output of lsof on the puppet master: .../... puppetmas 16418 puppet 617u IPv4 2683389 TCP puppetmaster.ircam.fr:57097->mysql2.ircam.fr:mysql (CLOSE_WAIT) puppetmas 16418 puppet 618u IPv4...

Lately it never fails when I attach a Mac running OSX 10.5 that I get runaway pid's. I tracked them down so far to multiple close_wait's: # /usr/sbin/lsof | grep pbg5mac smbd 24876 root 6u IPv4 80015755 TCP yoda.wrenkasky.com:netbios-ssn->pbg5mac.wrenkasky.com:49381 (CLOSE_WAIT) They can grow to over 100 if I don't catch it or nobody can log on anymore ;-) Anybody had any problems with Macs using...

We have a windows 2003 dc here at the university and I have successfully setup samba-3.0.2-6.3E on a RHEL WS3 machine. The problem is that after several hours, or several days winbind stops running and connections fail. I have seen instances of this on other sites, but no firm answers. I can provide files and logs if helpful

...on Solaris 9 and has 10'000 users (several hundreds at the same time). This week it died on us and when I inspected the machine, it was out of 8GB Memory and 16GB Swap because thousands of smbd processes were running. netstat -na showed that many hundreds of connections to port 445 were in CLOSE_WAIT state. We first thought it could be some sort of DoS Attack, but now I also discovered a lot of the following entries in smbd.log at the times the server became unresponsive: ---------------------------- 8< ---------------------------- [2007/10/25 15:40:30, 0] lib/util_tdb.c:tdb_chainlock_wi...

the rail application I have developed (really simple one 2 -> db tables with no more than 100 records) works perfectly in development / production mode on my windows desktop (win200 pro + mysql + ruby 1.8.2 + rails 1.1.6). when deploying the application on linux (ruby 1.8.4 , rails 1.1.6 the same mysql as on windows) everything *seems* to work fine. well atleast for the first few hours. the

...ways, but, I may have yet another instance of an issue on this. The puppetmaster system and the puppet system are both running 0.24.7-r1, on a gentoo system. Other puppet systems are running 0.24.4. The puppet system (not the puppetmaster system) that is running 0.24.7-r1 is showing multiple close_wait connections. The others are not. File changes are not affected; nothing appears to be stopping puppet from working, it is just that the 0.24.7-r1 client appears to be leaving connections unclosed. As other folks have noted, they don''t continually accumulate - they just appear (in m...

Hi folks I am running openssh-3.7.1 on my servers most of them are Solaris and Linux built. I run ssh-keyscan , some times it seems to be hanging ( even with -T option enabled) in close_wait state. can you please point me to any patch that is available or any work around for this problem ? thanks, Sai.

Hello! I can't find the cause of the above problem. Some smbd processes stuck in close_wait state and some file locks remain behind too. /any clue would be apreciated Attila /

...conds ( after doing analysis of our Rails logs and finding that all requests end under 60 seconds, and only 0.12% take over 1 second ). Pound closes these, but mongrel apparently isn''t getting the message and I end up with rapidly increasing socket connections on the app server all left in CLOSE_WAIT state ( which is when the remote end, pound, closes the connection, and the OS is waiting for the app, mongrel, to close it on its end ). Before setting Pound to kill these, one app server could effectively take out our web server, because of "Too many open files". The plagued app server...

Hi all, I encounter timeout errors during file uploads in my Rails application. I think the problem may be in the Mongrel configuration. Here is my setup: * Load balancer (Cisco CSM, my provider''s Catalyst 6509) * Apache 2.2.3 with mod_proxy_balancer * Mongrel 0.3.13.3 * Rails 1.1.6 * Ruby 1.8.4 * MySQL 5.0.22 * file_column I host an application in which users may upload medium files
