Hi, Upgrading to latest version of mod_jk solves the problem. As I said before, this on Windows 2003 Server running both httpd (2.0.59) and tomcat (6.0.13) on the same machine. We upgraded all production machines this morning.
Problem is in mod_jk 1.2.22 and is at least and fixed in 1.2.27. We did not do any other fixes to the environment when upgrading mod_jk. Hopefully this will help other people experiencing the same problem. /Jakob On Wed, Nov 12, 2008 at 9:29 PM, Jakob Ericsson <[EMAIL PROTECTED]> wrote: > On Wed, Nov 12, 2008 at 12:21 PM, Rainer Jung <[EMAIL PROTECTED]> wrote: >> Jakob Ericsson schrieb: >>> >>> >>> -- >>> Jakob Ericsson >>> +46 704 533 627 >>> >>> 11 nov 2008 kl. 22.37 skrev Christopher Schultz >>> <[EMAIL PROTECTED]>: >>> >>> Jakob, >>> >>> Jakob Ericsson wrote: >>>>>> We are also experiencing this problem. >>>>>> Our setup is running Windows 2003 Server with Apache 2.0.59 (no >>>>>> prefork), >>>>>> mod_jk 1.2.22 and Apache Tomcat/6.0.13. >>>>>> >>>>>> Will upgrading to latest mod_proxy_ajp in Apache httpd 2.2.X solve this >>>>>> problem? >>> >>> If you're willing to donate some time to this, please stick with mod_jk >>> and work with Rainer/Mladen to fix whatever might be wrong.
