ERROR - I/O Exception occurred while writing or flushing the stream
We ran a load test for almost 15 hours. It ran fine till 12 hours. After that we started getting below errors. There were few hiccups in between also but system recovered but once these errors started system never recovered. Searched a lot but didn't get any concrete reason. Attached PegaRules logs for reference

Thanks Arvind but the link didn't provide much clue on the issue. The load was always on the system for 12 hours but not sure why it started getting those errors at that particular time itself and subsequently the JVM crashed with memory full error.
Thanks Arvind. Is there any way we can evaluate what is optimum number of requestors for a particular heap size. For example:- 200 requestors are ideal for 8 GB heap. How we can evaluate this ratio of "No. of requestors : Heap Size"
