[Mono-list] xsp/mod_mono and zombie processes

I experience exactly the same problem. I have a ASP.NET site running with mod_mono/Apache 2. The application is accessing a Firebird database.

The site is running on mono since version 1.0.4. I was frequently updating to new mono versions. The "zomie problem" appeared in Version 1.1.17 or 1.1.18 as far as I remember. Since the site is running despite the growing amount of zombie processes I restart the mono processes with monopanel every now and then. Until now I didn't find the time for further investigation.

Yesterday I run the site with XSP only (no apache/mod_mono) on a new Mono 1.2.1 installation but the problem is still there. I use the Linux Mono installers from the Mono website on Fedora Core 6 and Debian 3.1. I am using XSP (not XSP2) and Firebird 1.5 with an older driver from the IBPhoenix site. Additionally my application uses log4net. No process calls or external programms.

Please tell me if you need more information.

Thanx in advance,
