We have problem with our openshift installation. We have 2 clusters each has a node (pod) running with GW 9.4 version. Last week, we have updated both clusters' memory from 4gi to 8gi. Since then 1st cluster does not have any problems however 2nd cluster consistently getting java.lang.OutOfMemoryError exception after running the pod for around 10 min.
2020-04-06T08:54:55.666+0000 SEVERE 148 org.apache.tomcat.util.net.JIoEndpoint: Error allocating socket processor java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:717)
Release : 9.4
Component : API GATEWAY
We also set at the same time : io.httpCoreConcurrency=4500 and io.httpMaxConcurrency=6000
Increasing the pod memory settings to 8gb is not enough for running io.httpCoreConcurrency=4500 and io.httpMaxConcurrency=6000
