Folks - I have been struggling for two weeks now to resolve an issue where web client cannot login due to error "A Network Service Error has occurred". I have research this issue within forum and googled issue no much luck. There are some solutions to old post where certificate has expired, so renewing certificate solves issue. There is also a bug reported in 8.0.0 when adding appointments to calendar with no attendees BUG LINK, I have tested this scenario and this is not my case. I am providing some basic info hoping this triggers someone to assist is resolving issue.
A) Running Ubuntu 10.04.4 LTS
B) Zimbra Open Source 8.0.3
C) Running Zextra mobile and chat
D) I have recently procured and successfully installed commercial certificate though this was after issues started happening.
The following are new items done right before issue started happening"
A) I have added new domain
B) I have changed one of users from email@example.com to firstname.lastname@example.org without creating a new one. I have also created new ones from scratch
The following is what I have been doing to resolve issue
A) reboot system giving that it is a quick fix. I realize it is not best practice. I will try to see if I can login to admin client, I have not tried this.
B) Monitor system. I have seen the Message Volume spiked to 7,557,024, not sure how to interpret this number, if you can shed some light here would be nice
C) I have not tried to login to other domain but will do that next time it happens. This is happening consistently every other day now.
D) I have looked at audit log but can't see anything that stands out though I am not 100% technical
Please let me know anyone out there has any thoughts on solving this issue.
