Known Errors

These are the known errors in our products, logged as reported with versions and platforms affected as well as corrections and work-arounds.

This list is largely historical, since it records all problems that have been reported throughout G&R history. Only the most recently reported problems still exist, unless you are using a very old copy of the product, in which case you should update the product to the most recent version.

E0138: Glink, CPU usage appears to be 100% when Glink runs

Product: Glink
Status: Closed, fixed in 5.2 and later
Last updated: 1996-09-18 14:09:24

CPU usage when Glink running, as shown by WINMETER or
SYSMON, appears to be 100%.

This is not actually a problem when running normal
Windows, in that Glink is simply utilising *unused* CPU
cycles to perform background tasks. Any application
that needs the CPU will find that there is in fact not
a problem, and despite the apparent lack of CPU
resources no degradation in execution speed will be

This is, however, not exactly the case when running in a
32-bit environment, where although the usage of 'spare
CPU cycles' will not affect other 16-bit applications
running in the same virtual machine, it will affect the
apparent usage of cycles in the 16-bit Windows
environment, and result in possible degradation of
32-bit applications.

In release 5.2, two options were provided to cater for
this situation:

  Settings -> General -> Message based mode
  Settings -> Communication options -> Use notifications

The second of these is only available for the serial
port, Windows Sockets and Atlantis interfaces (however,
this covers a major proportion of actual usage). When
both options are enabled, Glink runs in a mode where
background processing is reduced to a minimum and will
most often use no CPU at all when idle.

From release 5.4, both options are enabled by default
for new configurations.
