When the server is unresponsive, you can generate a stack trace for each IQ thread by creating a file named DumpAllThreads or dumpallthreads in the $ASDIR/logfiles directory (the %ASDIR%\logfiles folder on Windows platforms).
This feature was introduced in Sybase IQ version 12.5 ESD0002. For more information, see the section “Sybase IQ stops processing or stops responding” in the Sybase IQ Troubleshooting and Error Messages Guide.
