Check the dev_server and std_server logs from the work directory.

Have you done any modifications to the system prior to this?

Check all the JVM parameters to see if they are set correctly and recommended.

Thanks for the reply. The above logs are for std_server and dev_server0 files. The only error which is prevalent is

"[Thr 140217223493376] *** ERROR => Can't load main class [com.sap.engine.boot.Start] [jhvmxx_mt.c  1045]"

There has been an OS Patch Upgrade activity, and after this activity, we are getting this problem.

Please provide any suggestions for the above errors in the logs provided.

What about the JVM logs from the work directory? What version of JVM are you using on the system?

It appears to me that the issue is with the JVM. Check the JVM used by the SAP instance and if required update the Java and restart the instance.
