JVM was unable to create a thread #725
Description
I am using Spring boot for the application. There is a particular controller, when called, makes a couple of independent requests using OkHttpClient. I am using a threadpool of 200 threads to make these calls. It works absolutely fine in local environment. However, when deployed to cloud foundry, it shows up error as follows.
I have reduced the number of threads to 100 but the problem still remains. These are the memory settings in my CF instance -
Instance Memory Limit 8192 MB
Memory Quota 3072 MB (available memory 1024 MB)
Disk Quota 1024 MB
This is the error -
