WAS 5.0 plugin causes error "apr_proc_mutex_unlock failed" on IHS 2.0.42 res

I'm getting the following message in error_log when I restart IHS with
"apachectl graceful". This only happens if I have the WebSphere 5.0 plugin
loaded.

[Mon Oct 27 16:35:34 2003] [emerg] (22)A system call received a parameter
that is not valid.: apr_proc_mutex_unlock failed. Attempting to shutdown
process gracefully.

Here's the entry in httpd.conf that loads the plugin:

LoadModule was_ap20_module /usr//testwebsphere/bin/mod_was_ap20_http.so
WebSpherePluginConfig /usr/testwebsphere/config/cells/plugin-cfg.xml

The server appears to restart ok but the message is a little disconcerting.
Any idea why it is doing this?

Environment:
- IHS 2.0.42 on AIX 5
- WebSphere 5.0 on AIX 5

Bruce.
