Hi all,
I have a java program which runs repeatedly by calling to main functions in a loop based on a condition ..But after running for some time(say 30 minutes),it shows the follwing error and it terminate the program execution.But as per my requirement i want to run this program for several hours or time without showing any error and terminating the program. Exception in thread "main" java.lang.StackOverflowError at sun.nio.cs.StreamEncoder$CharsetSE.implWrite(Unkno wn Source) at sun.nio.cs.StreamEncoder.write(Unknown Source) at java.io.OutputStreamWriter.write(Unknown Source) at java.io.BufferedWriter.flushBuffer(Unknown Source) at java.io.PrintStream.write(Unknown Source) at java.io.PrintStream.print(Unknown Source) at java.io.PrintStream.println(Unknown Source) at pitstop.automation1.main(automation1.java:18) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) at pitstop.automation1.main(automation1.java:298) Could anyone please tell me what is the exact reason for this and how to fix this error.

Here i am calling the main function again and again using automation1.main(args) at line no 299 and 304. Please help me in this issue. regards, sanat

Hello sanatkumar and welcome to the Java Programming Forums
![]() Can you please tell me what is the purpose of this application? The error you are getting is thrown when a stack overflow occurs because an application recurses too deeply.
