IBM HTTP Server and the WebSphere Plugin - ws_config_parser: handleLogEnd: Failed to open log file: ' /opt/IBM/Websphere/plugins/logs/webserver2/http_plugin.log', OS Err: 2

I saw this issue this evening: -

[Thu Nov 12 20:07:47 2015] [error] ws_config_parser: handleLogEnd: Failed to open log file: ' /opt/IBM/Websphere/plugins/logs/webserver2/http_plugin.log', OS Err: 2

when starting IBM HTTP Server 8.5.5.0.

I checked my IHS configuration file - httpd.conf - which contained: -

WebSpherePluginConfig /opt/IBM/Websphere/plugins/config/webserver2/plugin-cfg.xml

and checked the Plugin configuration file itself: -

/opt/IBM/Websphere/plugins/config/webserver2/plugin-cfg.xml

which contained: -

   <Log LogLevel="Error" Name=" /opt/IBM/Websphere/plugins/logs/webserver2/http_plugin.log"/>

Note the obvious ?

Yes, there's a space between the quote and the leading /: -

   <Log LogLevel="Error" Name=" /opt/IBM/Websphere/plugins/logs/webserver2/http_plugin.log"/>

Once I removed it: -

   <Log LogLevel="Error" Name="/opt/IBM/Websphere/plugins/logs/webserver2/http_plugin.log"/>

IHS started without problems.
