java.lang.LinkageError: javax/el/ExpressionFactory : Getting this error message

[Manjunath MP]

Hi All,

We have started getting below error message on most of the admin functionalities.

This is resolved when I do complete restart, followed by re-indexing. But restarting during business hours is not recommended.

So request your assistance, if you have encountered this error message.

500 - Sorry, we had some technical problems during your last operation.
