panik: one special file in briefcase crahes mailboxd : how to remove?

[gruad23]

Release 6.0.2_GA_1912.UBUNTU8_64 UBUNTU8_64 FOSS edition.

Yesterday evening I uploaded a copy of my local documents-structure to my zimbra-accout using webdav.

Now I cant access zimbra anymore:

$ zmcontrol status
Host zimbra.goldfisch.at
antispam Running
antivirus Running
antivius Stopped
ldap Running
logger Running
mailbox Stopped
zmmailboxdctl is not running.
mta Running
snmp Running
spell Running
stats Running

and when I look into /opt/zimbra/log/mailbox.log

By now I dont care how to fix this ZLIB-bug, I just need to get zimbra get online again. Its weird that one file seems to bring the whole zimbra down.

I cant delete the file via webdav cause mailboxd is not running and zmmailbox needs mailboxd running as well.

Am I doomed?
At least I'm definitely panicking !!

ps: I tried to restart zimbra with zmcontrol and even /etc/init.d/zimbra stop|start as root

What error(s) do you see in the log when you try to start Zimbra?

This is a confirmed bug in the meantime, but the problem is not as severe as it seemed in the beginning.

The file really makes mailboxd crash, but its not stored in the briefcase so there is no need to remove it. The webdav-client had the file still in its cache and whenever mailboxd was started again, the smart client tried to "upload" the file and made mailboxd crash again. (at least dav2fs under linux is prepared for interrupted networkconnections and server-downtime and will sync its cache after reconnecting)

Solution: unmounting/disconnecting the webdav-client *and* (this is very important) manually purging its cache. the webdav2-filesystem in linux maintains a disk-based cache and even if you delete the problem-file on your harddisk, its still in the cache and will make mailboxd crash again and again ....

see details at : https://bugzilla.zimbra.com/show_bug.cgi?id=42833

the bug is still serious but if you disconnect the webdav-client/clean its cache you can at least start zimbra again.
