Issue/Introduction

I am receiving an intermittent unauthorized error when testing the OPS/MVS OPSVIEW Web Service in Google Chrome to the mainframe Tomcat sever (OPSWS). If I recycle the server, then the process flows though fine. My event is present in the OPSLOG. But, the subsequent attempts fail with an authentication error. I am wondering if there is a setting or parameter in the tomcat server that is causing this condition.

STDOUT of OPSWS:
ÝOS390LoginModule¨ authentication with RACF succeeded
userID = #dbis
ÝOS390LoginModule¨ added OS390Principal and OS390PasswordCredential to Subject
ÝOS390LoginModule¨ completed logout processing
ÝOS390LoginModule¨ authentication with RACF failed.
