<td>Unable to resolve current connection. Please check your connection
settings.</td>
<td>This message usually appears when you select to get profiler files
form device via TraceViewer for the first time, and the connections
settings have not yet defined.
<p>To resolve the problem, click <strong>Connection
Settings...</strong> to open the dialog where you can select the
correct settings for the connection you want to use. After saving the
settings, click Refresh Plug-ins List and continue with tracing. For
more specific instructions, see <a
href="../../tasks/analyser/an_load_trace_files.htm">Importing Profiler
Data files</a>.</p>
</td>

<tr>
<td>Could not read available plug-ins from device. See Troubleshooting
topic from Help.</td>
<td><p>This message appears when the connection settings have been
defined, but the information for the plug-in list cannot be fetched.</p>
<p>To resolve the problem, test that the Tracing service connection is
working:</p>
<ol>
<li>Click <strong>Connection Settings... </strong></li>
<li>Select the connection you are using and click
<strong>Edit...</strong></li>
<li>Select the <strong>Test Connection</strong> tab</li>
<li>Select the Device OS</li>
<li>Select Tracing as the service to test</li>
<li>Click <strong>Initiate Service Testing</strong>.</li>
</ol>
<p>If the connection works, but you still get the error message, makes
sure that PI Profiler is installed on the device.</p>

<td>Received corrupted data! See Troubleshooting topic from Help
<p></p>
</td>
<td>This message appears when try to use a USB connections for profiling
several plugins, and the connection cannot handle the amount of data.
<p>To resolve the problem, try profiling fewer plugins; or, if you need
to profile several plugins in the same trace, change to TCP/IP Musti
connection. For more specific instructions, see <a
href="../../tasks/analyser/an_load_trace_files.htm">Importing Profiler
Data files</a>.</p>

<td>Multiple problems have occurred. Jave heap space.</td>
<td>This message can appear when you try to import a large profiler date
file.
<p>Although Carbide.c++ reserves a large block of memory for the Java
Virtual Machine (JVM) to run the whole IDE, in some cases, the trace
import process may fail due to out-of-memory situation. This is usually
due to the Profiler trace log being too long in time and/or CPU load
being extensively high over the use case. The out-of-menory may also
lead to instability issues with Carbide itself, in which case the error
is shown.</p>
<p>This problem can be avoided by keeping the profiled use cases
shorter (the recommendation is maximum 5 minutes), and by selecting
only those Profiler plug-ins that are needed for analysing the use
case. Shorter use cases (in time) and smaller amount of selected
profiler plug-ins also ease up the analysis phase, since it is easier
to a browse shorter set of data and to pinpoint the possible
performance issues within the trace.</p>
<p>If you need to analyse longer use cases, there are also other tools
available for long-period-testing (LPT). For example, you can run the
Nokia Energy Profiler (NEP) directly on target and it can be used for
LPT type of use cases.</p>
