SERVER.EXE
While the system was loading an NLM, it found that one or more of the
module's public variables had been defined previously. An NLM cannot use a
previously defined public variable, because system integrity could be
compromised. This error is not fatal. The NLM will continue to load until all
previously defined symbols have been listed to screen. The NLM will then be
unloaded and all resources will be returned to the operating system.
Contact the vendor of the NLM about updates or patches.
SERVER.EXE
The partition is running out of redirection blocks. If the Hot Fix redirection
area is not increased, the disk will not be able to use Hot Fix to correct future
I/O errors.
The disk is probably failing. Troubleshoot or replace the disk.
SERVER.EXE
The module could not be initialized. The server will probably receive a
message from the module that explains why the initialization failed.
Refer to the module's message.
SERVER.EXE
This error indicates a corrupted NLM or a faulty disk system.
Reload the NLM from the master CD-ROM or diskette, and check the disk
system for potential problems.
