J2EE engine hangs on status Starting Apps

Hi All

We are currently experiencing issues with our J2EE engine. When we start it, it goes up to the status Starting Apps and never leaves that status. There are no errors on any of the logs/traces under work directory or the server0/log directory.

We are running EP 700 with Kernel Patch 146 on windows 2003 server. If anyone has seen this type of issue, please advice.

I have attached a java dump from std-server0.out file. I hope that helps

Whenever there is a hang or slow performance situation in j2ee engine, one needs to take a few threaddumps on the server and dispatcher processes. In case of 'Startng applications' hang situation, take 5 threaddumps at an interval of 1 minute each. The threaddumps are directed to std_Server0.out file. Please open this file with the Angel's threaddump viewer (SAP Note 1044373, 1020246). You could check for the blocked threads (which hang the engine), runnable threads in the same state over the course of theaddudmp (making system slow), the no. of free application threads - if 0, it means the engine has run out of applicaiton threads. Configure MaxThreadCount of ApplicationThreadMananger for server to 250+ (mostly required by most of the applications, some XI apps need over 350).

Last but not the least, one should also check garbage collection logs. Multiple back to back GCs could slow down the system. In this case, check if the JVM parameters are maintained as per note 723909.

If you are seeing high CPU usage on the system during the hang/slow performance, refer to note 742395.

Hope the above helps.

Snehal

Hi

Thank you everybody for the input. It turns out it was trying to connect to my CRM application (more esp the UWL which was installed). The CRM system wasn't working and therefore starting it resolved the problem. Question now is, is that normal?

Hi,

Can you paste us dev_jcontrol, dev_bootstrap, std_bootstrap.out so that we can drill more in to the issue.

Check out the link below which will help you to analyse the problem

Hi!

Please check the garbage collection of the server process. When it seems to hang in 'starting applications' it might just be 'garbage collecting itself to death'. If this is is the case, you might have to disable one or the other application and/or increase some memory parameters.

Kind regards,

Jörg
