A variable called DEBUGLOGFORMAT is defined. Its value is TRUE. (ENV

Additional Considerations
Following are some configuration considerations that can affect system performance.
Configuring OSS Servers for Effective Space Allocation
When you start the PATHMON environment, the PATHMON process allocates enough
memory and disk space to support most configurations. If your environment uses all
allocated memory and disk space, the PATHMON process attempts to get more.
You will not experience any increase in your memory and disk space requirements if
you configure an environment supporting only Guardian servers; an environment
supporting Guardian servers and a few large OSS servers; or an environment
supporting Guardian servers and many small OSS servers. On the other hand, if you
configure a large number of OSS servers with close to maximum-length attributes, you
will see memory and the PATHCTL file increase accordingly.
In rare instances, the PATHMON process may use up its allocated space and request
more space from the Guardian environment; or all pre-allocated extents for the
PATHCTL file may become full. If the PATHMON process uses all its allocated space,
it cannot perform any system functions while it attempts to allocate more space. When
