Putty fails to open additional terminal windows with ESSO-LM running

Information in this document applies to any platform.

Symptoms

Issue is seen with ESSO 11.1.1.5.1 on WindowsXP. When opening multiple putty terminal windows (with LM agent running ) at some random point no additional putty terminal window can be opened.

When starting multiple additional terminal sessions none of them will be displayed on the screen. However the windows Task Manager shows all putty processes - even the ones that fail to be displayed onscreen.

It is possible to close the already opened terminal windows, proving that putty is still responsive.
Shutting done LM agent suddenly makes all terminal windows appear.
It seems that under certain conditions the LM agent is preventing the terminal sessions from getting displayed.
