Since we upgraded to Release 7.1.2_GA_3268.DEBIAN5_64 we randomly get Internal Server Error when trying to access the Admin Console. Sometimes it will work however about 70% of the time when going to the link https://mydomain.com:7071/ we get the Internal Server Error message.
This is the error I'm getting in the mailbox log:
Everything else is working fine. RAM shouldn't be an issue.
