RE: too many open files issue in tomcat
I think you will get better help by providing the following: -Which tomcat version are you using? -Which OS are you deploying on? -What is your memory setting for tomcat (if explicitly set)? -What's your file descriptor configuration in the OS (if explicitly set)? -does the problem arrive alongside an out of memory error? -are there any 'IO heavy' processes that run on your deployment machine along with tomcat (DB, etc)? -Original Message- From: dasari@wipro.com [mailto:dasari@wipro.com] Sent: Monday, June 27, 2011 12:54 PM To: users@tomcat.apache.org Subject: too many open files issue in tomcat Hi, I am facing the issue of "too many open files" in the tomcat and not able to process any request further.

RE: [mod_jk] problem serving URIs with 'special characters'
Hi; Sorry for the beginner's question but does this means that I need to compile mod_jk1.2.25 against my apache 2.0.52? Or can I still use the 1.2.25 from the tomcat connector downloads page as a drop-in replacement.

RE: [mod_jk] problem serving URIs with 'special characters'
Thanks; one question though. The downloads page states that mod_jk1.2.25 is for apache 2.0.59 and later only. i have a 2.0.52 installation(on centos) that i can't change. does this mean i am stuck here? or can mod_jk1.2.25 still work with apache 2.0.52 thanks in advance. -Original Message- From: Rainer Jung [mailto:[EMAIL PROTECTED] Sent: Sun 8/26/2007 11:33 PM To: Tomcat Users List Subject: Re: [mod_jk] problem serving URIs with 'special characters' Guy Katz wrote: > Hi; (using: centos, apache 2.0.52, mod_jk 1.2.21, tomcat 6) > > Recently, I encountered a problem with URIs that has 'non western > European' characters (for example: > http://www.somehost.com/roller/admin/entry/nofx_%D7%91%D7%93%D7%A8%D7%9A > ).

If you absolutely need to forward the original URI, you should set JkOptions +JkForwardURIUnparsed This has negative side effects: - if you rewrite the URL via mod_rewrite, and then forward via mod_jk, mod_jk wil still forward the original URI, not the rewritten one - the Tomcat AJP connector expects a session id that does not come via a cookie but via URL encoding as ";jsessionid=..." in the URI. It has to be a semicolon, not it's percent encoded equivalent. The last jk 1.2.25 has a new forwarding policy. It reencodes everything that does not seem save, and that way tries to forward a URI that should fit into most cases- I would suggest you try that version without any JkOptions. Also: with log level debug, it logs a line similar to: [Sun Aug 26 01:12:03.482 2007] [27669:0] [debug] init_ws_service::mod_jk.c (782): Service protocol=HTTP/1.1 method=GET host=(null) addr=127.0.0.1 name=fraxinus.entenhausen.zz port=8080 auth=Basic user=jung laddr=127.0.0.1 raddr=127.0.0.1 uri=/auth.jsp for every request. The line includes the URI exactly as it got forwarded to Tomcat, so you might be able to debug your problems more easily. The line exist also in the debug log of earlier versions, but for them does not include the uri. > My questions are: > > 1.Should the JkStripSession help in this case?

JkStripSession is only important, if your static content gets served by Apache, but your webapp added URL encoded sessions to the links. > 2.How should I solve this?

RE: [mod_jk] problem serving URIs with 'special characters'
I am not sure what you are reffering to by saying URLencoding but:
the default jkoption value in the mod_jk in the version i have processes the
URI in a way that changes its value. that is why i changed it to
+ForwardURICompatUnparsed but than i encountered the image loading problem.
i would be happy to hear ideas but please be more specific.
thanks.

URLEncoding doesn't take care of this problem?
In Response To:
Hi; (using: centos, apache 2.0.52, mod_jk 1.2.21, tomcat 6)
Recently, I encountered a problem with URIs that has 'non western
European' characters (for example:
http://www.somehost.com/roller/admin/entry/nofx_%D7%91%D7%93%D7%A8%D7%9A
). I noticed that apache was forwarding to tomcat a different URI than
the original which caused problems in my site.
Digging into the subject I found the JkOptions +ForwardURICompatUnparsed
fixed my problem. However, I then encountered a different problem then.
On the first hit, some images were not displayed in the browser (not
served to it). So I checked the forums and found out about the
JkStripSession. I figured it might help so I turned it on but nothing
happened.
My questions are:
1. Should the JkStripSession help in this case? Was there a known
bug in my apache/mod_jk versions related to this (couldn't find in
bugzilla)?
2. How should I solve this? The only thing I need is to be able to
forward URIs with 'special characters' as is to tomcat for a specific
application (context)
I am really out of my element here so I would appreciate your help
greatly.
Thanks in advance
