Zimbra AJAX Webmail not loading

[zanthius]

So, thanks for the tip on checking crontab, I found something slightly different to yours, right down the very bottom:

*/15 * * * * sh /opt/zimbra/log/zmswatch.sh;

It looks like it calls another executable file in /opt/zimbra/log/ called zmswatch

That was using 200% CPU. Killed it and removed the crontab entry.

Love to know the entry point for this, but we have an older version
Release 8.6.0_GA_1153.SLES11_64_20141215151129 SLES11_64 FOSS edition, Patch 8.6.0_P7.

We had exactly the same issue. And I saw that the files had the wrong permissions (executable instead of writeable).

Version: 8.7.11_GA_3800.NETWORK

I did the following (as root);
cd /opt/zimbra/mailboxd
find webapps -type d -exec chmod 0755 {} \;
find webapps -type f -exec chmod 0644 {} \;

Then restart Zimbra;
su - zimbra
zmcontrol restart

After that, everything working fine again and no such messages in the logs anymore.

This also solved our problem. Thanks a lot.

Followed AB_Zimbra's solution fixed half of the problem.

Thanks AB_Zimbra!

Now login advance mode is fine but can't add attachment.

Error uploading file.

Any idea?

By using smartphone sending attachment is ok.

Thanks

There were problems from zimbra, entered the command in the console
zmfixperms
After this, the zimbra client web part has stopped loading.
Helped
cd / opt / zimbra / mailboxd
find webapps-type d -exec chmod 0755 {} \;
find webapps -type f -exec chmod 0644 {} \;

Then restart Zimbra;
su - zimbra
zmcontrol restart

I am sure that the problem is zmfixperms

Thanks for solving the problem !!!
