Unable to launch applications using panel.

Could be a file descriptor leak due to a faulty panel plugin and you have 
reached the maximum number of files open allowed per process.

Assuming that your system is Linux, get the pid of the panel (e.g. ps -ef | 
grep panel), go to /proc/<pid>/fd and count the number of files in there 
(e.g. ls -C1 | wc).

Then check this value against OPEN_MAX defined in /usr/include/...

Similar method may be applied for Unix providing a pseudo /proc fileystem such 
as SunOS.
