I've had a test server up and running for about 4 months. Using CentOS5 and NE 4.5. Went to login yesterday and the Zimbra Admin page comes up blank. Everything but antivirus is running.
When I try to login as one of the test users I set up, I get:
'An unknown application error has occurred. Please correct any errors and retry. If the problem persists, please contact your System Administrator. (AjxException.INVALID_PARAM)'
googling that hasn't really helped me much though this one is pretty close.
Invalid_PDU error (OS 4.5)
Anyone ever seen a similar error. I am weak on troubleshooting linux, so if you have any tips or tricks I'd be indebted if you shared them with me.
