Note: Repost of Assert failed, buff too small. We are currently troubleshooting a problem (originally posted last week 3/20/02) relating to this same issue. Our application uploads data using an HTTP POST. Directly to Tomcat or with HTTP, it works fine. With HTTPS, ajp13.java reports "Assert Failed, buff too small", and then the application produces an exception. We are using the O'Reilly servlet with our environment, outlined below. Anyone with any assistance would be appreciated.
-----Original Message----- We are having a problem with Tomcat using an upload servlet to upload potentially large files (up to 100MB). The servlet works fine for all file sizes in the following instances: http://servername/app/UploadFiles.jsp http://servername:8080/app/UploadFiles.jsp but when using https (ie: https://servername/app/UploadFiles.jsp, we get 'Page Cannot Be Displayed'. A summary of the error logs is below: IIS_Redirect.Log ---------------- [Wed Mar 20 15:49:20 2002] [jk_ajp13_worker.c (206)]: sending to ajp13 #8192 [Wed Mar 20 15:49:20 2002] [jk_ajp13_worker.c (258)]: received from ajp13 #3 [Wed Mar 20 15:49:20 2002] [jk_isapi_plugin.c (426)]: Into jk_ws_service_t::read [Wed Mar 20 15:49:20 2002] [jk_isapi_plugin.c (426)]: Into jk_ws_service_t::read ... this repeats 1364 times, everytime, before the following: ...

Win2000 Server, patched up to latest levels - Tomcat 4.0.1 Binary distribution, running as a service - IIS 5.0, using ISAPI_Redirect.dll dated 12/08/01 (Thank you Henri Gomez!) - SSL Enabled through IIS - I have several servers with similar environments. Some servers have multiple logical web servers with multiple Tomcat instances. This particular server has only one instance of each. However, the same behavior is observed on any server/instance with SSL. Facts: ------ 1] This only happens on https://, all other forms work fine. 2] This only happens on files larger than just under 11MB (11,172,378 bytes, plus or minus a few bytes for filename payload). 3] The "Assert Failed" error comes from Ajp13.java, Ajp13Packet.java, or MsgAjp.java. I am not a Java programmer (yes, another one of those 'systems' guys), but was able to dig throught the source to find the actual system.out lines. 4] 11,172,378 / 1364 = 8191+-, the same size as the ajp packet. Why 1364 ajp packets? Anything smaller works fine. -----Original Message----- From: Christopher Bare [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 26, 2002 4:16 PM To: Tomcat Users List Subject: Re: How to POST very large data to Servlet? (a question about ServletRequest.getInputStream) You should look for information on Multipart requests. It's a modification of the standard http request that uses a format similar to that used by the SMTP email protocol. It's used for uploading files from a browser to a server. I think Struts has a handler for multipart requests, and there is another one available at servlets.com in the package com.oreilly.serlet. good luck, -Chris --- Zhidong Yu <[EMAIL PROTECTED]> wrote: > I want to use HTTP's POST method to send some very > large and unknown > length data to server.
