Both Tomcat server have the same version 8.0.14 and also Java 8. These are the settings from the

问题 Is there a Tomcat 8 cartridge for OpenShift? I know that you can install Tomcat8 in a DIY cartridge, but I was looking for a faster and easier solution. And if there is one, how can I install it and how can I migrate an application from jbossews 2 (tomcat7)?

问题 I have a Spring Boot application running on two servers. It accepts file upload requests (approx 1 KB) via Controller from 1000s of IOT devices. Additionally there is a TCP Listener which also accepts GPS data as a Stream from these IOT devices. I have setup the Tomcat max thread count to 3000 on one server and 5000 on a larger VM. After a day or two my Spring Boot application freezes, i.e. it stops responding to any further API calls. One reason, I suspect is that the IOT devices are not

问题 This question already has answers here : Unsupported major.minor version 52.0 [duplicate] (26 answers) Closed 4 years ago . I have codes compiled on JDK 1.8.

问题 While upgrading my Artifactory server (free OSS version) from the version 5.2.0 to the latest 5.4.5, I was hit by an ARTIFACTORY_PID problem. After migrating from 5.3.2 to 5.4.0, the Artifactory server did not want to start anymore complaining about PID file /var/opt/jfrog/run/artifactory.pid not readable (yet?) after start.
