Thread dumps are essential for diagnosing production issues. This article introduces an additional troubleshooting pattern and outlines various methods to capture thread dumps. Analyzing thread dumps for Exceptions or Errors is crucial, as demonstrated by a java.lang.OutOfMemoryError case. Tools like fastThread can assist in identifying problematic threads efficiently.
Threads that throw exceptions, like java.lang.OutOfMemoryError, should be examined for the source of issues. In this case, insufficient memory allocated for processing large XML payloads led to the error. Increasing the memory allocation resolved the problem, highlighting the importance of investigating exceptions in thread dumps for troubleshooting application issues.
