Corba timeout issue

[Bibhu_Bikash_Na]

Hello All,

Whenever we are trying to invoke any process that uses generatePDFOutput service. We get corba time out error in the log for the first time The same works perfectly fine second time. We have increased every possible timeout in the server such as JTA, MaxStuckthread timeout etc. Still it does not gets fixed. Restarting the server helps only for sometime. After few hours we again get those issues. The environment details are given below.

AEM Forms JEE 6.5 + Weblogic 12.2.1.3.0 + Linux + MS SQL Server 2016. The errors are given below.

Caused By: java.io.EOFException: Attempt to send message on closed socket
