Issue/Introduction
How to resolve "java.lang.OutOfMemoryError: unable to create new native thread" errors in BW?
Resolution
Cause:
1). There is not enough memory to create a thread.
2.) MaxThreads on the Linux server is too low.
Workaround:
1). Try the following by modifying your application.tra file.
- Reduce Stack Size.
- Reduce Heap Size if it is very large.
- Set "EnableMemorySavingMode" to true.
2). Increase the Threads-max in server:
sysctl –w kernel.threads-max=150000 (default value: 57786)
